...therefore we can assume that Londons streets are the safest, right? Speed Kills, so a lack of speed will not, right? So no more speed cameras, 'traffic calming', or other irritants. No need to lower speed limits or increase penalties for exceeding them. It's all sorted. London has the safest streets in the world!! We should be proud.

Britain's traffic woes are worse than continental Europe's because Britain's public transport has failed to keep pace with modern needs. For 50 years Britain has had a culture of putting the car and its needs first, then giving public transport the crumbs if there happen to be any. This is in stark contrast to continental Europe where good public transport has always been a priority rather than relegated to bottom-of-the-heap. These countries never had a Dr Beeching come and destroy their local railways, or a John Major to come and privatise what was left. And generally any railways which did close were left intact to facilitate future reopening. Not so in short-sighted, we-know-best Britain where lines were ripped out and the land sold off piecemeal. Same with trams. Britain threw all its away while foreign cities built theirs up. Now Britain is reaping what it has sown, which is a culture of rampant, choking, car-dependency.

I have lived in both London and Hamburg and any comparison
of their traffic situations is a waste of breath and column-space, as the two are so diifferent in every way.

Looking at my cycle computer; my average speed for the last 148miles of Cycling in London is 12.8mph. I don't put that much effort into cycling fast and even stop at red traffic lights!
