What EVERYBODY is missing here though, is that doesn't mean the AI can't get unrealistic good traction and acceleration out of the previous corner exit, meaning that they get closer to that top speed way before your car does.
Which is exactly what is happening.
The AI all of a sudden is the master of braking, apex holding and exiting corners at full throttle to the point where they can approach ANY skill level of player as if they have unlimited KERS. IF anything, I'd say that's exactly what it is. The AI has a hidden KERS button which allows it to get massive acceleration out of corners that IMO is not possible for players to get.
Regardless of what the so called definition of rubber banding is, this method still essentially means that the cars end up somehow going inexplicably faster than you on a straight, which is precisely the thing people don't like about rubber banding......
Try the BAC Mono on the Pro Tour event...then read your own statement again.
