The definition of dangerous driving is that you are not in control of the vehicle. A friend of mine overturned this penalty in court.
He was a BSB privateer, and was pulled for speeding (100+) on the m/way. They tried to throw the book at him for dangerous driving. Because the crown is prosecuting you, you can get free representation, which he did. His brief demonstrated that he was in total control, despite his speed. Charge was dropped, and just a got a few points and a fine, which is a big difference toyour driving record for insurance etc. He was able to prove his ability because of his racing career, which could also be done by anyone who races or has a racing background.
It is always worth putting as much pressure on the system as possible, especially if an over zealous copper is throwing the book at you. If you have done something horrendous, and are just getting a slapped wrist, then its best to shut up and move on, but if they are being excessive, then take them on. I did it, and when it got to the magistrates court, the coppers notes were inconsistent and the brief picked him to pieces, as he probably didnt expect it to go that far. Magistrates are only civilians with no legal qualifications, so a good strong justified common sense arguement can go in your favour. As long as you dont alienate them by losing your temper, or by showing disrespect, and just put across your case in a decent articulate way, you take the CPS on and win. Dont fall for the tricks of prosecution lawyers, who will try to make you agiated by cutting you off mid sentence and put words in your mouth to try and make you angry, which obviously makes you look bad. Just stay cool, look the magistrates in the eye and be sincere. They get just as pissed off with the old bill bringing ridiculous cases like this to court.
