Just checked you out! The whole saving time while speeding etc was the part of the course that made me think about it not doing it again, as the course speaker said, saving 5min tops on most journeys.
I guess it is just the thrill that makes me want to drive fast! I have been on a couple of the super car experiences, guess I'll have to purchase a couple more as I doubt I'll be taking my 150pd to a track day any time soon!!
