Ok, so handicaps are not going to be track specific. I see the logic behind it, good for people doing seasons on lots of circuits. The cars will, however, be genuinely balanced on a small number of tracks. Any track where the RB4 was competitive before will now be RB4 dominated. So it's not as much help for the majority of racers who just pick-up and play, same problem, different cars.
Still, FXO seems slower overall, which was the main objective in TBO I suppose.
