Cycling in Sydney Australia
The saying goes "we need this like a fish needs a bicycle", but if it wasnt for the fish we wouldnt be able to walk, or cycle.
That was interesting. I was reading some time ago (possibly Wikipedia) about the question of why nature didn't invent/evolve the wheel and part of the discussion pointed out that in most natural terrain, legs work a lot better.
So now we have these wonderful machines for converting legs into wheels, all we need is some better terrain...
