If you behaive like a twat you get treated like one, that is absolute madness and someone who displays that lack of judgement should be sent to prison. Just to add to what nilrem said, twice the national speed limit is no garuntee of a custodial sentance. The fastest speed I saw was a biker who was caught at 145.9 mph, he was banned for 6 months and realised just how lucky he was.
