Gyratory traffic schemes, extended one - way systems etc

even dutch standard is still much too small, bear in mind amsterdam is a lots smaller than London, the average dutch commuter is 1.8 miles, whether the Londoner is roughly 5 miles.

I'm not sure what you mean Ed. What 'Dutch standard', and why do you bring in figures for average commute length? (The figures for average commute lengths from the Netherlands that I've seen varied between 1.8 and 2.7km (I think, but would have to check, it could be miles), and for London it's altogether more difficult to find any kind of meaningful measure. What isn't in doubt is that average commutes into London are much longer than in urban centres in the Netherlands, just saying by how much exactly is pretty difficult (and actually not that important).
