You'll lose and it will be costly. If you have any less than 9 points it really isn't worth it.
I don't have any points, I've driven 30,000 + miles every year for the last 15 odd years and in that time only picked up 3 points on 2 occassions. I don't drive fast and I don't think that I am above the law, but for some reason this penalty feels particularly unfair, as if I am being used to swell the Government coffers, as motorists always are. I'll decide when the penalty notice arrives.
