True, but then it doesn't matter if you were see sawing down the M1 on a bogey, if you've got crap thinking time, you've got crap thinking time. I think the point is moot. Whether you have discs the size of a wagon wheel and callipers like mini coopers or discs the size of a washer, it all goes back to driver habits, so for those of us who do have a decent thinking cap we can experience the benefit of larger brakes and what not, to avoid drivers who have poor thinking/reaction times and/or skills.
