I've got a bunch of friends who are in their 30's who are still into skateboarding . It's kind of cool, because it's not only a form of transportation, but it's an art form, and exercise, and it can even be a job.
Skateboarding can also be considered a recreational activity, an art form, a job, or a method of transportation.

Skateboarding
Skateboarding is an action sport which involves riding and performing tricks using a skateboard. Skateboarding can also be considered a recreational activity, an art form, a job, or a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue with 11.08 million active skateboarders in the world. In 2016, it was announced that skateboarding will be represented at the 2020 Olympic Games in Tokyo, Japan. Since the 1970s, skateparks have been constructed specifically for use by skateboarders, Freestyle BMXers, aggressive skaters, and very recently, scooters.
Rodney Mullen
John Rodney Mullen (born August 17, 1966) is an American professional skateboarder, entrepreneur, inventor, and public speaker who practices freestyle and street skateboarding. He is widely considered the most influential street skater in the history of the sport, being credited for inventing numerous tricks, including the kickflip, heelflip, impossible, and 360-flip. As a result, he has been called the "Godfather of Street Skateboarding." Rodney Mullen won his first world skateboard championship at the age of 14; over the following decade, he won 35 out of 36 freestyle contests, thus establishing the most successful competitive run in the history of the sport.
Lewis Marnell
Lewis Kristian Marnell (3 December 1982 – 18 January 2013) was a professional skateboarder from Melbourne, Australia who was Slam Magazine's 2008 "Skater of the Year". Marnell died in January 2013, following complications related to type 1 (juvenile) diabetes, a condition that was diagnosed when he was 10 years old. Numerous tributes were published following Marnell's death and his longtime skateboard deck sponsor, Almost Skateboards, continues to use the hashtag "#LewisMarnellForever"—on 15 and 29 July 2014, the company published the hashtag with 2006 video footage of Marnell skateboarding in Japan.
List of Regular Show characters
"Regular Show" is an American animated series created by J. G. Quintel. The series contains many characters, with seven main characters and various recurring and one-time characters. Mordecai (voiced by J. G. Quintel) is a 5'10" anthropomorphic blue jay (6' including the crest) who works as a groundskeeper at The Park. He has been best friends with Rigby ever since childhood, and together they are very lazy and constantly slack off at their jobs there. Mordecai is more conscientious, mature, and moral about his actions than Rigby is, which sometimes leads to his opposing Rigby when he is the cause of some kind of chaotic problem.
Daewon Song
Daewon David Song (born February 17, 1975) is a Korean-born American professional skateboarder, recognized for his skillful technical street skateboarding. He is a co-owner of Almost Skateboards, along with Rodney Mullen, and also skates for the company alongside other sponsored team riders. Song was named the 2006 "Skater of the Year" by "Thrasher" magazine, an award that is widely considered to be one of the most significant honors in skateboarding. Song, a Korean American, was born in Seoul, South Korea, and grew up in Gardena, California, following a year spent with his grandmother in Hawaii, US.
Willow Bunch, Saskatchewan
Willow Bunch is a small community located in south central Saskatchewan, Canada, southwest of the provincial capital of Regina. The population was 286 at the 2011 census. Previous names for Willow Bunch have been "Hart-Rouge" and "Talle-de-Saules". The area has seen influences from Métis and Fransaskois. About 19 kilometres north-west of Willow Bunch is one of Saskatchewan’s biggest archaeological mysteries. The St. Victors Petroglyph site is a provincial park that is host to over 300 rock carvings. The carvings are located on a sandstone cliff that is elevated at 950m. The uniqueness of the plateau is characterized by being only one of five sites in Canada where petroglyphs are on a horizontal structure of a rock.

I think it's dangerous as form of transportation.  Someone could easily get hurt.

You just have to wear a helmet!  Pads, if you're really nervous.  There are, after all, about 11 million skateboarders in the world.  Can't be that dangerous...
A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue with 11.08 million active skateboarders in the world.

Bicycle helmet
A bicycle helmet is designed to attenuate impacts to the head of a cyclist in falls while minimizing side effects such as interference with peripheral vision. There is ongoing scientific research into the degree of protection offered by bicycle helmets in the event of an accident, and the effects of helmet wearing on cyclist and motor vehicle driver behaviour. There is active debate over what can be concluded from available studies, and on whether the use of helmets by cyclists should be promoted or mandated, either just for children, or for cyclists of all ages. In particular the debate over bicycle helmet laws is intense and occasionally bitter, often based not only on differing interpretations of the scientific and other academic literature, but also on differing assumptions and interests of various parties.
Protective equipment in gridiron football
Protective equipment in gridiron football ("football gear") consists of equipment worn by football players for the protection of the body during the course of a football game. Basic equipment worn by most football players include helmet, shoulder pads, gloves, shoes, and thigh and knee pads, and a jockstrap or compression shorts with or without a protective cup. Neck rolls, elbow pads, mouth guards, hip pads, tailbone pads, rib pads, and other equipment may be worn in addition to the aforementioned basics. Football protective equipment is made of synthetic materials: foam rubbers, elastics, and durable, shock-resistant, molded plastic.
Lola Pearce
Lola Pearce is a fictional character from the BBC soap opera "EastEnders", played by Danielle Harold. She is introduced as the granddaughter of Billy Mitchell (Perry Fenwick) and Julie Perkins (Cathy Murphy), and an extension to the already established Mitchell family. Lola made her first appearance on 12 July 2011. Her storylines have mainly focused on her relationship with her family, a teenage pregnancy after a one-night stand with her relative Ben Mitchell (Joshua Pascoe), fighting to keep newborn daughter Lexi out of care, her friendships with Abi Branning (Lorna Fitzgerald), Jay Brown (Jamie Borthwick) and Dexter Hartman (Khali Best) and a relationship with Peter Beale (Ben Hardy) despite their families' disagreements.
Disc brake
A disc brake is a type of brake that uses calipers to squeeze pairs of pads against a disc or "rotor" to create friction. This action retards the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. Development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad.
Lacrosse
Lacrosse is a team sport played with a lacrosse stick and a lacrosse ball. Players use the head of the lacrosse stick to carry, pass, catch, and shoot the ball into the goal. The sport has four versions that have different sticks, fields, rules and equipment: field lacrosse, women's lacrosse, box lacrosse and intercrosse. The men's games, field lacrosse (outdoor) and box lacrosse (indoor), are contact sports and all players wear protective gear: helmet, gloves, shoulder pads, and elbow pads. The women's game does not allow body contact but does allow stick to stick contact. The only protective gear required for women players is eyegear, while goalies wear helmets and protective pads.
Health issues in American football
Health issues in American football comprise a large number of health risks associated with participating in the sport. Injuries are relatively common in American football, due to its nature as a full-contact game. Injuries occur during both practice and games. Several factors can affect the frequency of injuries: epidemiological studies have shown older players can be at a greater risk, while equipment and experienced coaches can reduce the risk of injury. Common injuries include strains, sprains, fractures, dislocations, and concussions. Concussions have become a concern, as they increase the risk of mental illnesses like dementia and chronic traumatic encephalopathy (CTE).

It's dangerous for other people. You might be safe wearing a helmet and pads, but what about the person you run into on the sidewalk?

You just dismount briefly, if you're concerned about a collision.  Plus, there are skateparks, places specifically designed for skateboarders to practice and work on their tricks.  There's a whole culture around it that's been around since the 70s.
Since the 1970s, skateparks have been constructed specifically for use by skateboarders, Freestyle BMXers, aggressive skaters, and very recently, scooters.

Skatepark
A skatepark, or skate park, is a purpose-built recreational environment made for skateboarding, BMX, scooter, wheelchair, and aggressive inline skating. A skatepark may contain half-pipes, quarter pipes, spine transfers, handrails, funboxes, vert ramps, pyramids, banked ramps, full pipes, pools, bowls, snake runs, stairsets, and any number of other objects. The first skatepark in the world, Surf City at 2169 E. Speedway, Tucson, Arizona opened for business on September 3, 1965. Patti McGee, Women’s National Champion, was here for the grand opening. It had concrete ramps and was operated by Arizona Surf City Enterprises, Inc. A skatepark for skateboarders and skaters which had plywood ramps on a half-acre lot in Kelso, Washington, USA opened in April 1966.
Freestyle BMX
Freestyle BMX is bicycle motocross stunt riding on BMX bikes. It is an extreme sport descended from BMX racing that consists of five disciplines: street, park, vert, trails, and flatland. In June 2017 the International Olympic Committee announced that it was added to the Olympic program for the 2020 Summer Olympics. The earliest photographic documentation of BMX freestyle shows Devin and Todd Bank in 1974 riding BMX bikes on an eight foot tall skateboard ramp they built at their childhood home in West Los Angeles, California. This was the birth of BMX ramp riding. Devin Bank was also documented doing 360 degree freestyle spinning tricks on the street and also in the air by jumping off curbs.
The Berrics
The Berrics is a private indoor skatepark owned by professional skateboarders Steve Berra and Eric Koston. It is also a website providing content filmed in the skatepark, as well other skateboard-related media. The facility's name is a portmanteau of the owners' names (the "Ber" of Berra's surname and the "ric" of Koston's first name). In an interview with "Pop" magazine, Berra revealed that prior to the launch of The Berrics, he had been offered a million-dollar deal to direct a film based on a screenplay that he had written. Due to filming commitments for his skateboard deck sponsor, Alien Workshop, Berra declined the offer and later commenced work on The Berrics concept following a period of reflection: All I wanted to do is I knew we have this hook because there were a lot of kids that always would ask Eric and I about our building.
Street skateboarding
Street skateboarding is a style of skateboarding that focuses on tricks and transitions in public places. Street skateboarders skate in urban streets, plazas or industrial areas, making use of park benches and picnic tables, guard rails and handrails, planter boxes, bins, stairs, retaining walls and other street furniture not purpose-built for skateboarding. Competition street skateboarding is conducted in purpose-built skateparks designed to replicate real-world urban environments featuring purpose built benches, stairs and rails alongside traditional skatepark elements like vert ramps and funboxes.
Ethnomusicology
Ethnomusicology is the study of music from the cultural and social aspects of the people who make it. It encompasses distinct theoretical and methodical approaches that emphasize cultural, social, material, cognitive, biological, and other dimensions or contexts of musical behavior, instead of only its isolated sound component. The term "ethnomusicology" is said to have been first coined by Jaap Kunst from the Greek words ἔθνος ("ethnos", "nation") and μουσική ("mousike", "music"), is often defined as the anthropology or ethnography of music, or as musical anthropology. During its early development from comparative musicology in the 1950s, ethnomusicology was primarily oriented toward non-Western music, but for several decades has included the study of all and any musics of the world (including Western art music and popular music) from anthropological, sociological and intercultural perspectives.

Certainly, skateboard parks are fine, but on sidewalks and on the road, skateboarders pose a risk to other people.

Agree to disagree, I suppose.  Skateboarding has become so mainstream and -- for the most part -- socially accepted, that it will be one of the sports represented at the 2020 Olympics in Tokyo.

Tokyo bid for the 2020 Summer Olympics
Tokyo was selected by the Japanese Olympic Committee on July 16, 2011 as Japan's bidding city for the 2020 Games. The city is moving forward with its bid following the March 2011 earthquake and tsunami which affected much of eastern Japan. Prior to Tokyo's selection by the Japanese Olympic Committee, Hiroshima expressed interest in hosting but withdrew their plans to bid. On September 7, 2011, the Japanese Olympic Committee announced that Tokyo Governor Shintaro Ishihara will be Chairman of the Tokyo 2020 bid committee. The bid committee held their first meeting shortly after. Towards the end of November 2011 the Tokyo 2020 Council was established.
The Man-Eating Myth
The Man-Eating Myth: Anthropology and Anthropophagy is an influential anthropological study of socially sanctioned cultural cannibalism across the world, which casts a critical perspective on the existence of such practices. It was authored by the American anthropologist William Arens of Stony Brook University, New York and first published by Oxford University Press in 1979. Arens' primary hypothesis is that despite claims made by western explorers and anthropologists since the 15th century, there is no firm, substantiable evidence for the socially accepted practice of cannibalism anywhere in the world, at any time in history.
Bids for the 2020 Summer Olympics
There were a total of six bids which were initially submitted for the 2020 Summer Olympics. Tokyo was ultimately elected as the host city at the 125th IOC Session in Buenos Aires, Argentina, on 7 September 2013. The Olympic bidding process begins with the submission of a city's application to the International Olympic Committee (IOC) by its National Olympic Committee (NOC) and ends with the election of the host city by the members of the IOC during an ordinary session. The process is governed by the Olympic Charter, as stated in Chapter 5, Rule 34. Since 1999, the process has consisted of two phases.
Madrid bid for the 2020 Summer Olympics
Madrid 2020 was a bid for the 2020 Summer Olympics by the city of Madrid and the Spanish Olympic Committee. The last time the Olympic Games were hosted in Spain was in 1992 when Barcelona hosted the XXV Olympiad. This was the only time the Olympic Games were staged in Spain. Madrid was nominated by the Spanish Olympic Committee on June 1, 2011. It was then approved by the government a month later. On September 8, 2011 it was announced that Alejandro Blanco, president of the Spanish Olympic Committee, would preside the Madrid 2020 bid. Shortly after his appointment he defended Madrid's ability to host the games despite Spain's current economic problems arguing that the games would be an investment.

I think it's socially accepted as a sport but not as a mode of transportation.  I doubt that it is even legal to use a board on the sidewalk.
