great - you overlay cycleways on a 1:1250 of the City. I'll take a look at the result. I'm not holding my breath.It is not "physically impossible". It may be politically undesirable, and expensive. But that is not the same as physically impossible.
Amsterdam has plenty of segregated cycleways in areas where traffic volume and speed is high. Look at streetview. Of course, there is no segregation on narrow quiet streets - but that is because traffic volume is low, and (thanks to traffic design) it's actually quite unpleasant to use the car. The Dutch - sensibly - do not segregated everywhere. But the key point - the one that needs to be continually restated - is that the Dutch design streets so that people feel safe on bikes, and that their journeys are more direct and convenient than by car.
That is why large numbers of people use them to get about in Holland, and why modal share in London is flatlining.
Simply telling drivers to "share the road" gets us nowhere. You or I might feel approaching comfortable going around Elephant & Castle, or Hyde Park Corner. At least 90% of other adults will not.
This is the fundamental problem.
(Not sure where your response to the quotation issue has gone btw - Trikeman has quoted something, but it has disappeared)
As for the safety thing - life's moved on. The bomb-dodger generation of cyclists took to London't roads because they were fearful of taking the tube. They did the sensible thing and piled straight down the main roads, ignoring LCN+ which became more or less obsolete overnight, and totally disregarding the DfT advice that roads of 10,000 vpm were not suitable for cycling. They swept down the A24, the A3, the A12 and even the most ardent admirer of CS7 would concede that actually the job was done for TfL by cyclists of all types simply taking to the road. Where once I used to go round the Elephant on my own, now women on shoppers with high heels do the thing without a second thought.
Now, take a look at the people riding bikes in London (not least the hire bikes). They're a broad cross section - by class, gender, age (possibly not by ethnicity). These people have decided to ride a bike. The people who don't have decided not to ride a bike. They may do so in the future as more of the main roads reach a critical mass, but, in the mean time the hire bikes have broadened the image if not the demographic of cycling and their success can only mean that more people associate cycling with the everyday. It's all good and getting better.
Now show me the 1:1250 plan.........because otherwise I really am not interested. It's not wanted, it's not affordable, it's not sensible and the best bit is it's not going to happen.
As for WalthamForestCrapBlogger - I can't be arsed.
