You really should not be doing this. You know that right? You do realize that because of the "rubberbanding", by you pulling over, you're effecting everyone else on the track? You will be causing the rest of the racers at the front to have GARBAGE handling? This is just as bad as those "drifting" in online events.
It would be different if we had private rooms, then everyone would be on board. But, we don't. You are imposing your will upon others.
No. Rubberbanding causes the handling to deteriorate from the front to the back. And it gets worse for THEM the more laps YOU get down.
If I were racing and saw people doing this sort of thing race after race, I'd be reporting PSN ID's to Sony without even thinking twice.
The only concern you show for "the others" is "when the race starts pull over to side of track (try to avoid hitting other drivers)". After that you have no concern what so ever that you are ruining their gaming experience. Which is probably dangerously close to violating your EULA.
People have been reported for abuse for continuously cheating.
Don't use the actions of idiots to justify YOUR actions.
