Oh, and over here standard commute speed is 85mph anyway (is that the same in the US?). Motorway racing is a bit tricky, as you'll get banned if caught over 100, so the only really fun stuff is the twisty bits in the highlands, borders, dales and Wales, as you can stay under the speed limit and still push things.
Although on my latest run up to John'O'Groats I was sitting at a fun speed (with still a wee margin for error as it was snowing) and a CityLink coach shot past me like I was sitting still.

Erm...frightening!
