What do you expect PD to do? There is just a fundamental difference between controlling a car with the tiny stick on a gamepad and an actual steering wheel + pedals. They are not going to 'fix' that in a million years. It is probably a miracle in itself that the difference in performance is this small to begin with. Also gamepad users might actually have the advantage with rallying. It is what it is.
I know it is difficult to expect perfect steering on controllers too, in all scenarios and all ways of steering (joystick, buttons, motion control..) but what I would wish for is actually to give us settings to control "interpolation", or "in-betweens", or however is the english word for it. I mean to achieve 1:1 ratio if end user want it.
Check in my example here under, watch the video, second 40-45 -ish when I am passing chicane, especially second part of chicane when I need to pass last bollard, so as you can see in lower part of video, which shows both my hands, and steering wheel in the car, I rotated my hands....aaaand... aaand.. there is proper delay ( I mean proper in hundreds(tenths) of seconds, that is what we are chasing here) until steering wheel in the car reach position of my hands.
THAT is what I wish for. And not only on steering but on acceleration too. I do compare video replays and I when I compare a replay from someone on wheel/pedals vs controller, you can floor pedal and it will reach 100% as soon as your foot press it all the way, while when I press accelerate button, R2, it has small delay of "in-betweens" or something like traction control, until my acceleration reach 100% and in some cases it is not so noticeable but in some it is and it cost controller users time.
So my wish, hand out "interpolation" settings to users so we can adjust that.
Look for this part of video, see below, video link is at the bottom.
