I was thinking about this the other day whilst cycling in London. It would be fairly easy to create a network through London for cyclists and only cyclists. All we would need to do is put a side certain streets as cycle ways where cars were not allowed to travel down. All of these streets could decend onto central london, with orbital streets connecting them all up. So it would become like a spider web. Of course, we would not have to use busy roads. With some decent planning, I'm sure a good network could be built using side roads. Of course, people living on those roads will want car access, so perhaps an exception can be made for them.

And it will be good for the car drivers! It should encourage more people to cycle, so there will be less cars on the main roads and therefore less congestion.

What do you all think?
