There's enough legal off street racing meets these days that there shouldn't be any excuse to do that sort of thing on public roads. Going for a spirited drive on your favourite moutain or coastal road is one thing, but actually racing or driving at dangerously high speeds on the roads, in particular in built up areas, is not on. After witnessing someone in a wheelchair crossing a road get hit by a car that was speeding through the intersection, I always think of that everytime I'm tempted to 'have a go' It's just not worth it. :(
