In the UK, where roads are rarely designed for the speed limits posted, it doesn't stop anyone from driving dangerously fast. So I don't really buy this argument. Cars simply handle and drive too well these days for the road to be an impediment. Especially in the UK where most cars have summer tyres, unlike the all-weather tyres common in the US. If anything, it encourages the wannabe-racers to drive fast for a challenge.
