Does the higher air pressure from behind actually provide net thrust. If you neglect that you still have some air resistance, rolling resistance from the tires on the ground and various frictional losses in the bike. Overall, since the record on rollers indoors is higher (200 mph iirc) it seems being pulled being a vehicle isn't a huge benefit.
