I race crutch rockets all the time...who wants a wasp on your tail that will push you to a near crash. Let them pass then have their hair stand on end coz they cant shake you to 150mph. when its over give the polite sportsmanship wave...i.e thanks.
If a situtation arises with other traffic or a squeeze be a gentleman and BACKOFF...then back on the gas. A getoff on a bike hurts. I raced motocross.
Please the M3 already has a reputation of rich punk kids behind the wheel...lets get some respect back from the other motorists.
Watch your back mate...he will find you...
