Hey go for it, I'd love to see a driving workshop. Although you say it will be small, I'd like to see the cars have basic features like acceleration and brakeing tilts model. Hard turns rolls model realistically, not like the driving code that come with the studio. Seperate movement for the wheels so to allow for realistic suspension, and rear wheels that spin with throttle.

Well what ever you plan is going to be a great start. Plus by making it a simple one would mean it'll be released faster.
