Not just controllers but other settings too.
With the MRT last night for example, I had to stop and turn on the virtual mirror, the little mirrors weren't doing it for me. But then I jump into a road car and now I have two rear view mirrors.
Also, I like to open up the FOV a bit with the BF1, so I can see the mirrors. But with the FOX, it feels too stretched out.
Also, in the cars where there's info on the wheel, I want the wheel on. In all other cars I want it off. It just gets in the way of the gauges and I already have a wheel and arms infront of me anyway.
It seems like everytime I switch cars, there's a few settings to change, and then I forget something so I have to go back in...
It'd be great if FOV, Virtual mirror, Wheel and arms, Controller settings, were tied to the car somehow.
