ooh flippin heck Ed I dunno! I don't have detailed figures for traffic in every city in the land.
We were talking about *severe* day-long traffic problems outside the normal morning and night rush hours, yeah?
From personal experience, I'd not choose to drive in Leeds, Madchester or Bristol again. I understand Edinbourgh is bad, but I've never been there.
What I'm saying is that London is not typical of the rest of the UK. Even in 2nd city Birmingham a car is far the best option outside the rush hour
So I dunno half a dozen maybe??
C'mon on then tear away .........get it off your chest.
(which is seems you've all been doing, judging by how much this thread has grown since I left it last night
