1. "all in one" part selector: Like the tuning menu, you could add all the parts you wanted on the car, then click apply, and they would all be applied, rather than waiting for the game to reset the car each time, it would just do it once. Of course, you'd be able to check a "live updates" box like on the tuning menu if you wanted the old system 2. A box that automatically applies power steering top all vehicles that have it. This would be much better than having to go through the parts selector every time I spawn a new car to get an authentic driving experience. The steering feel with power steering is quite good, and maybe this should be defaulted, as I dont think there are any side effects of power steering for people who are using either a gamepad or a keyboard
Well, you can pause the physics while in the parts menu, select what you want & resume physics; they will all apply at once
