The BF1 car is a bit rough and it needs to be improved 
There should be adjustable and more realistic traction control, also adjustable fuel mixture ratio. Auto clutch should be removed (there is a paddle clutch in a real F1 car) and of course handbrake should be removed.
I don't know whether there is possible to adjust brake bias live currently (without going to pits) but it should be possible also.
I know its not a easy work, but simulator like LFS should simulate these features
