It didn't fix every breach spot, only the well known ones on the 'ring. The big thing is your car now gets reset to the track if you manage to get out, but only if you get so far away from the course. I found a spot where you can drive under a banked corner on indy but it's pretty useless.
Oh and the OCD update was shit for me, the only cars in there that I didn't already have were 2 Diahatsu's, and 2 other worthless shit cars.
