They haven't really affected me... But here is my little rant about experiences
Those who have seen my car would agree it is a magnet, hard to miss so needless to say as soon as i think of doing something stupid, chances are i would get caught because if the choice was there of pulling over a commodore speeding or pulling over a hot pink import speeding than unfortunately the pink import will be the obvious target...... Yes alot of the time we are targeted because of what we drive but if you dont give a reason to get in shite than you have no worries...
Thus the reason i stick to the speed limit, yes I occasionally hammer it off the lights TO the limit, and very rarely actually feed it to it but i don't do it all the time and no skids etc....
I love my car and have respect for my car therefore i look after it, this also keeps me out of trouble with the police because i give them no reason to target me... I get pulled over ALOT just because they can but not once have they been able to pin me or warn me for anything..
That is all
