or find a motorway near you with a measured mile, its easy to find one, they have a series of small round signs usually on the side of the fast lane, and it marks the start, then in quarters till you reach the mile. and drive down it at 60mph with an assistant on the stopwatch. it should take a minute. post up the time on here & I'll do the maths.
