For example why have a four-way intersection come to a total stop so that pedestrians can cross in any direction. Why not have pedestrians able to cross parallel to the traffic flow, and any car-drivers turning should give way to them.
Oi! Ever tried getting anywhere on foot in Central London in the evenings? You spend ages hanging around waiting for the green man, and then it usually only allows you to get to the refuge in the middle of the road, where you have to hang around again for another light to change. I've missed buses and trains because of this.
And why don't pedestrian lights change as soon as you push the button? Why do you have to wait for several dozen cars to pass first?
And come to think of it, WTF is it the pedestrians who have to push a button and not the drivers?
I've always held that at any light-controlled road junction, all the pedestrian lights should stay green long enough for a 90-year-old granny with a zimmer frame to get all the way round the junction. After all, we'll all be 90-year-olds one day, with any luck.
PS I voted for Ken, of course, as did most Central Londoners. It's the suburbans who never use public transport that voted Boris - the same people who wrecked Ken's Fare's Fair campaign years ago. Not voting Tory is part of my non-religion, like not crossing picket lines.
