Just come in from a day at work on the road. There I am going down the road at 60mph. and there is this slower moving vehicle in front me. It is a small moblile crane and it has flashing orange lights on top of it. Queue of traffic in front of me and we were trying to overtake this thing with traffic coming the other way. Had a small truck in front of me and it had to sit behind the crane and the crane was going well-35mph up a slight incline of about 3% The truck was behind the crane for about 200 yards and then he pulled out to overtake.

I could not believe my eyes. 6" off the back of the crane and going for it was a cyclist. He was getting a full slipstream and was hardly turning the pedals. Rider was youngish but the bike was a Full Time Trial machine.So what vehicles do you slipstream to get up to speed?
