That same year also saw the release of two arcade games that extended the car driving subgenre into three dimensions with a first-person perspective: Sega's "Road Race", which displayed a constantly changing forward-scrolling S-shaped road with two obstacle race cars moving along the road that the player must avoid crashing while racing against the clock, and Atari's "Night Driver", which presented a series of posts by the edge of the road though there was no view of the road or the player's car.
