Oh man, Klik and Play.
Instant 10 for nostalgia right there.
There seem to be a lot of "you are a car and you dodge things" games made in KnP, Game Maker, etc., but this... well, it would be one of the better ones if not for the invincibility bug. And there's no music, which knocks it down a bit; if you want to keep people playing a very simple game that doesn't ever change, you'll almost certainly need good music. The bit about running over the little bastards in the middle of the road (er, well, "picking up passengers") is an interesting addition to an archetype (it's not big enough or varied enough to be called a genre) that normally revolves solely on dodging.
