I noticed that the position did not update on the GUI during the race. Its maybe too easy (already won all races and buy a few cars), and I find it easier to drive a worse car (maybe it's me)..
I'm not a fan of racing games but this one deserves every praise!
EDIT: Also, when i upgrade to max that most expensive car i can't drive without breaking too early so I can't use gas pedal to maximum (it is impossible to steer)..
