I was waiting for someone to ask, otherwise I just look long-winded.
The whole team races point, wing, mechanic, bruiser, and joker. Races can vary from two to four teams at once. Unless it's a show in which one team just loops the track looking good.
As a rule of thumb the cars have to have an engine and four wheels. I'm sticking with good 'ole rubber on this one though the cars are going to look more futuristic and streamlined. Each person's car is modded to their position. The point and wing are faster but less hardy, mechanic handles well but doesn't do much beyond in race catches with electromagnets (Can screw other racers with them too.) The bruiser is slowest but can take a lot of abuse and the joker is more or less up to the player but it can't over excel for obvious reasons.
Any racer can win it for his team. Oh and all-human players. No aliens.
You also have to pit, there are no multicolored healing strips (Ala F-Zero)
Oh no real weapons (Buzz saws, missiles, machine guns.) this is a planetary sport ordained and whatnot.
