I assigned circle for gas, triangle for brake, square for reverse, cross for hand brake, L1 for shift down, R1 for shift up, left analog for steering, right analog for look left/right, d-pad for RA menu adjust, R3 for opening RA menu, L3 for ghost, L2 for horn, R2 for toggle high beam.
The main thing about DS2 is the face buttons have a lot more travel and wider range in pressure input, basically I can press 3 time harder before applying full 100% brake or gas compared to DS3 face buttons. This is why I can modulate the brakes and gas from 10% to 100% at will with no difficulties. It made me possible to drive without ABS or any other aids, all without any issues that plaguing the DS3 or pedals, but the analog steering still can't compete with steering wheel.
