Firstly, apologies to anyone here how owns a high powered car, I'm sure you're all sensible drivers, but my observation is that car BHP is inversely proportional to IQ. Case in point, I was out with family on a walk this weekend, and witnessed two Porsche 911's tearing up the road (not together). These aren't wide open roads, but urban residential streets, with many side roads filtering in.
Pro motoring groups will say it's not speed that kills, but inappropriate speed that kills. Well sadly, I see a lot of inappropriate speed going on, and it's dangerous. Someone pulling out of a junction will not be expecting a vehicle doing 0-60 in 3 seconds, and I don't care how good those ceramic brakes are, they are not going to stop anything tanking along at that speed, with a fraction of a second reaction time available. Let's also mention pedestrians trying to cross the road.
There's also some doofus who drives around in a car which backfires louder than a chieftan tank firing rounds of ammo. I'm not kidding, you can hear this guy driving all over town from miles away, it's that loud. And the ****** invariably likes to drive around late at night.
I'd like to see a limit on car power when driven on public roads, because people just cannot be trusted to drive sensibly. Never going to happen though.
