The fact that the tw at driving the car was so full of himself, that he was filming the events shows the lack of intelligence. The fact that he was given 12 years is a miracle in the first place as we see too many idiots getting a slap on the wrist rather than a lengthy sentence. The usual problem is the lack of evidence - which was provided by the moronic miscreant in this case - and so the guilty party can usually come up with any number of "excuses" , usually "sorry mate I didn't see you" or "the sun was in my eyes" or "he came out of nowhere".
The whole sentencing system in this country needs reviewing, only when these morons realise they're going to prison for a long time will they get the message.
