A friend of mine was banned for 12 months becasue the police had to catch up to him at 125mph and stated that was the speed he was travelling in court. He was also convicted of "racing" another car when simply it passed him at a greater speed but was never stopped. My friend was speeding, but he wasn't doing 125mph, more like ~80 in a 60. They stopped him (Merc) but not the Astra that he was apparently racing. No speed camera recorded the offence, it was all on the officers word who was in an un marked Fiesta. pretty sad really, but as my friend was young and had a nice car they made an example of him.
