here I was thinking I can make a simple U-turn where the road decided to become a stair. Then I fell off the map. (don't go off the road, kids guys, your car will fall into an endless abyss and your all existence starts shifting colors like cray-cray.)
The driving system felt to mechanic and unreal. When you turn you expect the car to keep pulling you in the direction it drove before, not just completely change course. Unity got physics for that, I know it's probably gonna take a while to fix and adjust it, but for the sake of some realism... I believe you get it.
As far as I'm understanding, there's still no goal for the game, nor music and such. I think focus on the driving system (unless you like it that way), make a reset mechanic, and maybe make some ground around, though it would be cool driving a road which goes like a roller coaster above ground, but then make it apparent. The basics work.
Edit: refreshed and checked what happens when my fuel goes all down. First I fell off to the right, where there's a white chunk and got stuck (forever, can't reverse) and then I just pressed the gas pedal to empty the tank. and voila - nothing happened.
