Hello, I have ideas that look unfair

For driving a vehicle
PC is like WASD; make it easier to drive

But on mobile, there is the walk button

Why not make car control so you can hop in the car right away, and on mobile you can see the arrows, so it will be usable to turn much easier? Same on the Xbox or PlayStation controller; they have to use the joystick to change it.

Xbox Controller
(RT) to accelerate and the Left Trigger
(LT) to brake or reverse.

PlayStation
R2 Button to accelerate
(L2) to brake or reverse.

For both
Steering Left Analog Stick
