After learning about Unity’s lack of an auto save feature I am back with my finished environment.

I decided to scrap the idea of having canyon roads and went with just the city roads. So level wise I have a 9 block city made with two different building types, a garage inside one of the 9 buildings, stop lights, sidewalks & the streets themselves, and a mountain terrain around the map so players don’t fall off the edge of the world when they exit they get of the street.
The car model & all of its mechanics are not mine, I used Vehicle Physics Pro
