personally, i won't do it. i'll flash my lights to warn of danger, but not for speeding.
if you are all too dumb to be caught by a cop then you deserve the consequences. i see way way way too many stupid drivers on the roads as it is, we don't need any more thank you.
i'm not saying i don't speed, i'm just saying look out for yourself, especially you people in your beemers and mercs etc who think you're the best driver in the world, completely oblivious to everything around you.
i recently got my very first speeding ticket a couple of weeks ago, and i drive fast everywhere, but i still consider myself a much safer/better driver than the majority, for a number of reasons too. not a bad return on 13 years of driving, the first half of which was spent street-racing (in England, with corners, none of this crappy drag racing you guys do here in the States, somethng where the driver rules, not just the car).
anyway, i'm sure i've made no friends in this thread, but think about it. a lot of places we do need the speed limits, especially as people are so piss poor at driving that they pull out in front of you. drive fast, if you're capable (most are NOT) and where it's safe to do so, and keep your eyes open for the cops, if they can see you, then you can also see them. learn to drive whilst looking at the road ahead, not 50 feet in front of you.
and for you, with the 12 tickets and the lawyer for a Dad, you are very very sad (read dangerous) and i hope you eventually do lose your licence.
