Kinda lost the iteration aspect of this and just finished this prototype

up. So iteration 2 technically.
Cleaned up some CarLogic code, did todos notably the brake force.
Added the concept of wheels being on or off road and hampering
acceleration if off road.
Decided to do some camera work to get a better feel for
acceleration/speed.
Implemented Lap Timers, sections, and validation upon finishing a lap.
