Re: What an idiot....
Rule #1 - When you see a cop car behind you - be squeaky clean!
The argument is that even knowing a cop car was behind him, even not knowing the exact rules governing writs-jobs whilst driving. The cop car observing you trumps all - Just drive and keep your hands visible on the wheel (unless you need to change gear on a manual gearbox). Don't prod any button at all!
Rule #2 - Pay attention to the most hazardous thing likely to cross your path.
Rule #2 should really be equal to rule #1 as if you fail rule #2 in front of the coppers you're gonna get pulled anyway.
