I wouldn't take anything they come out with as fact without another source.
You are right about Clarkson, though - he is a troll, plain and simple.
Speed != safety.
Lines of code != productivity.
It teaches motorists that instead of watching out for dangers, they should be constantly monitoring their speedometer. It makes our roads less safe.
Jeremy Clarkson is awesome. He should be made a lord. The liberal lefties and the easily offended hate him. Which is fantastic to watch. 20,000 complaints to the BBC after he made a joke about strikes? How absolutely hilarious.
If only I'd have been driving on the road, going at 50mph, like that time when the car skidded on something on the road, and after hitting the edge flipped over and landed on its roof in a muddy ditch. Unlike the dangerous dents and scratches that my car park accidents have left my car with, this little minor incident only left the roof a little bit crushed in, and broke one of the wheels off. Also smashed out all the windows. So there wasn't even any need to call the AA, not like that time somebody opened their door into my car at 0mph and left a little nick in the plastic runner bar.
My only regret is that thanks to the nanny state I couldn't legally have gone at 100mph to make it even safer yet!
