Interesting video, well presented and clear. I do think you may have missed something though. In May 2023 there was a physics update, at the time I was a D-pad user, yes DPAD ...... and very, very close to A+ DR. Once that update was released I found the pad unplayable, utterly insane levels of understeer, I could not rotate the car at all, something really big happened in May 2023.
I find the search function on this site kind of tough to use but I was very loudly complaining in several threads the game was now unplayable for me. I had to put the game down and went off to play fortnite for a year before finally committing to a proper wheel. It took months to get used to a wheel but I cannot imagine using a pad again.
I realise some do not have the space or maybe the budget but if you can swing it, a decent wheel is immeasurably better, there's really no comparison and I recommend you make the transition if your situation allows for it. I have a fairly large rig (Titan) but have it on castors and this has been the key to ensuring our PS5 room is not hogged by my rig as I tuck it away after each session.
ANyways, check out the May 2023 update as I think that hurt the pad.
