my mum has followed coppers along a wide lone mainly straight built up road in taunton before, 30mph, my mum was right up his arse doing 25 and then he sped up a bit, mum now creeps up to 30 and hes still getting away. point is, they are allowed to speed, but we get points when we do, he didnt have no lights or sirens though!! they do it all the time mate, really, from all the stories ive heard, you need to take them with a pinch of salt
