I could make an infinite list of bugs, but here are the biggest ones:
When making the TINIEST crash into a fence, your car is flipped around completely causing you to, in most cases, lose the race.
Sometimes, when recovering, your car completely flips out and glitches due to the weird physics.
Sometimes, the car doesn't even start!
Overall, a fun game, just very aggravating.
Oh, also add a free play map/sandbox map where you can test the physics for all us shitty players out there, please.
