Try making a multiplayer version where one person/the creator of the game is the road controller and others bet on the cars to put up/down their ranking.
These cars are amazing. Two feats they've done so far: Top four cars left, I decide to make some action and throw a hazard out. Green gets hit, I'm like "AHAHAHA! SUCKER!" Then all of a sudden, it does a barrel roll and LANDS IT. Second one: Red gets hit in a chain reaction by blue being hit by green which was hit by purple, and it went on until first. NONE of them survived.
I watched a guy waiting for an elevator before I realized I need more than 1 elevator... He waited five days just for an elevator to the next floor. Haven't stairs been invented yet?
Thx~
