On mobile platforms, the vehicle automatically accelerates.
Touch the left and right edges of the screen to steer.
Touch the middle of the screen to brake/reverse
(this also temporarily stops acceleration).
- Fix braking not working correctly (and make breaking stronger
to make vehicles easier to control at high speeds).
- Allow using the D-Pad for steering and X/Square for braking.
- Tweak exhaust particles to be more subtle and fade more smoothly.
- Change spawn position to a location that's more straightforward
to drive.
