Hi,
Actually never tried to make one in arcade style physics.
Daytona memories…
Anyway I tried to achieve something like this with CarSetup pack, had some results, this is a few hour work and is far from polished.
Also gave it a try making a new setup with force and force torque like Space Dust, I get the basic setup and how it should react. The actual gas (push forward force) is relative to camera direction + force Self Z and force torque on Y axis Self, results where nice until in high speeds it got bumpy, had no suspension just a cube with 4 sphere colliders
The third version I believe is to cheat it all, a quick idea - object in size of road (width) that follows a track path. With player input control a car (inside the object) by translate or other move/rotate etc, also could use FloatSpring for shaking values.
If you want to try it out with CarSetup pack, PM me your email - will pack my test and send to you.
