Fraction over 190 indicated running down a slip-road between the A41 and M25 westbound at Watford. It's the longest, bit of road around these parts that I know of, and like DanaT I wanna see a LONG way ahead before I go for a highest speed stunt.
Maybe you think I'm a wheener not doing 180 every day Omega, but I have this inate fear of doing a 100+mph face plant into the back of a cage. The roads in the UK are just too damn short/twisty/packed with other people to permit that kind of stunt on a regular basis. I'd love to see how fast my bus will go, but short of hiring out heathrow airport for the afternoon, the only 200+mph that my bus will ever see will be on a Dyno.
Anybody else in the UK know a decent road, I'd love to hear it.
