I agree with most of you lot (conveniently). The guy was taking the p*ss. Sure, even if he is the best of the bunch when it comes to advanced driving, he does need to practice and master the car he drives, but why on earth at that speed?! At the end of the day you would want the driver to be competent if he was called to drive that fast in a real life situation- you wouldnt want any driver going so fast with no experience. But I refuse to believe anyone needs to go THAT fast, especially in an unmarked car (with no blue lights I should add).
Secondly, as has been mentioned, he should have authorisation to drive at that speed on any particular road, which he obviously did NOT have, hence being caught by other police!!
Thirdly- even if he is ***'s gift to advanced driving, I'm sorry, but at those speeds his reactions would be just as poor as anyone else, and it is simply dangerous to be doing what he was doing- his own own ability/skills only count for so much when he is driving out in the real world due to so many other factors.
And finally, it was a vauxhall!
