Should road cars be speed limited?

[AussieAV]

Let me start by saying I'm not advocating this. My first reaction as a car enthusiast is - Hell No! Designing and engineering for speed has produced some of the most desirable, memorable and beautiful cars in history. Can't even imagine how boring cars would be if they were all designed to stay within the speed limits.

The thing is that after reading the thread about the guy doing 220 km/h in his WRX (http://www.fordforums.com.au/showthread.php?t=11309395), I thought this is probably a question that the media and/or anti-car lobbyists will be asking very soon, and this guy has given them the ammo to do so.

The scariest thing is that when I think about it, it is hard to fault the logic behind it. What are the good reasons why a road car should be capable of doing these sorts of speeds? I'm struggling to think of any so thought I'd ask everyone for some input.

Best I can come up with is that people who want to legitimately enjoy their HP cars on a track day, but can't justify/store/afford two cars, should be able to do so. But this could be covered by systems like the Nissan GTR's that can have its limiter switched on/off based on GPS location.

I don't want a nanny state, but guys like this, make it easier for those who do, to get public support.
