I cant drive with high lock in my DFP. The wheel is very resistant to fast rotation and not realistic at all
But the 900º gives you a wide freedom of choice in lock angles
They only did this for 1 or 2 seasons. The transmissions are computer controlled anyway, so rather than have a driver to push a button or pull a paddle to shift, the computer was programmed to decide when to shift. Regardless of the source of the shift (computer or paddle shifter), the commputer controls the throttle (actually fuel injection cycles), clutch, and the actual shifting in a F1, GT1, and other types of race cars.
I get much the same laptimes with my G25 as I used to get with a PS3 controller...but I have much more fun in the process, it feels better, it's more realistic, and I don't develop RSI
