I can't see why you would want to drive in London - it's a great place to walk and has a far better public transport system than anywhere else in the UK. Amsterdam has the right policy for cars.

The problem we have with cyclist out here in the Yorkshire countryside is that they go out in packs, riding two or three abreast on narrow country lanes and not moving. I've nothing against cyclists as such - I'm one myself - but I do object to this antisocial behavior.
