Insurers are already doing it with their black boxes. I'm 30 and Admiral (my current insurer) wanted to fit a black box....I told them that they were stupid and to give me a quote without the box, and it was cheaper than they were saying it would be with it. I've been driving for 13 years and, to quote the AA excerpt in the Sky link above, "use a burst of speed to get out of dangerous situations".
The amount of people that are on their phones, smoking, not paying attention and generally driving like a **** is incredible. Speeding is very low on the amount of crashes/deaths on our roads; it's education and driving to road conditions. There are many times when 30mph is too fast in towns, same as 70mph in snow/torrential rain isn't clever either. But, when it's a bright sunny day with clear visibility I drive how the car should be driven.
I've just driven 150 miles to Dumfries area and saw far too many overtakes across solid white lines, blind corners and junctions; it's insane. I overtook three cars as they were following a caravan and all doing 38mph. I might have gone over 70mph but it was much safer than following behind them adding another hour onto my journey.
Anyway, after all of that, the Sky news thing does seem like it's just inciting comments and forum posts like this one, so it's done it's job in getting visibility.
