 This makes life easier. It's all for our convenience and laziness. Most of what we invented is just so it's easier for us to do. We don't have to do it no more. We just push a button and there you go. On the other hand, if these driverless cars and trucks led to fewer traffic fatalities, wouldn't that be a good thing? I mean, we've got about 50,000 people a year who die on the freeways.
