Watching Top Gear leads me to think otherwise.

I've seen (various TV shows) all sorts of things driven on public roads in the UK that would have the police tasering you here in Aus'.
Not sure of the situation now but speaking with an F40 owner here for Targa once I was told you can't legally run an F40 on the road here (day to day).
Anything like the purportedly legal in the UK trackday specials (Radicals etc) would be impossible I reckon.
I would love to be proven wrong on this though.
Talking of police, I'm just home from a friend's birthday party that was shutdown at 11.30 PM (on a Sat' evening) by the police... My daughter and I were talking to the host's 95 year old Grandmother at the time - so you can imagine just how wild the party was... bloody kill-joys...
