I've often wondered about trying out a recumbent bike. This morning I saw one crossing Tower Bridge*.
The rider's head was nicely placed at the height of the bumper behind and the exhaust in front, with nothing that might indicate his presence at the eye-level of any driver (or indeed cyclist).
So if I do give it a try one Sunday morning in Dulwich Park, that'll be the end of it.
*Yes, I know this picture shows one at the Arc de Triomphe (and I bet she didn't ride the recumbent round it), but it's the only picture I could find that shows one in relation to a car (now I wonder why that could be?).
