There really is no need to be quite so agressive joko - it makes you appear a bit, well, odd.
"People, by and large, know how to drive sensibly: should we punish those perfectly safe drivers who regularly, and safely, drive at 80mph on a motorway by electronically limiting their cars just because of a few idiots? Seems unfair to me."
I genuinely believe the vast majority of people know how to drive sensibly - if this were not the case there would be caranage on our roads.
80mph on a motorway is, indeed, breaking the law - but in the right conditions, it is a daft law: this is pretty much borne out by the fact that other than for the most officious of coppers, the police will turn a blind eye to it. I've lost count of the times I've driven past a police car on the motorway at 80mph, and yet I've never, not once, been pulled over.
Further, artificially limiting cars to a low speed, such as 70 on a motorway, is, I would argue, dangerous - there are times when it is necessary (and not for any perceived 'cool' reasons) to exceed 70: for example - I have had to increase my speed before on a motorway to 90mph in order to pass cars on my left and pull in to allow a police car to pass me. There was no room to move left without doing so because the motorway was busy, and had my speed been artificially limited I would have impeded the police car's progress.
If you hit something or somebody at 70 or 80, the results are going to be pretty much the same - death and injury - so I'd be surprised if the saving lives argument holds much water. Plus if people cannot safely drive at 80, then I'd be surprised of the could safely drive at 70 either and therefore probably shouldn't be driving at all.
British motorways are the safest roads in Europe because we generally have a better standard of driving - Yes there are idiots, but I just can't accept any argument that would advocate hindering the vast vast majority just because of a tiny minority: this is the same argument that suggests the way to stop drunkeness is to ban booze.
