My knees tend to hurt when doing this stuff. However finding a good position in my rig seems infinite task. Main issue is probably me not driving for real, so body is not used to it and now getting old
I haven't yet, mainly because the game hasn't given me a reason to. Like with heel toe I had to learn or perpetually crash while threshold braking. Haven't had any "persuasion" to double clutch - if so I'd have to learn it I guess - sounds hard, but i guess like anything you get used to it.
