I fully accept that some road users put other road users at risk. I'm a cyclist; I frequently see drivers in traffic tapping away at an SMS on their lap. What I do not accept is that the rights of vulerable road users are being eroded.
As I said, mobile phones are a recent phenomenon, they didn't exist twenty years ago, they are a distraction and the practise is relatively unpoliced. That's an example of how things have got worse for cyclists. Take the explosion in traffic use in the last twenty years, way over and above any increase in cycling rates. In London policies are being pursued at the expense of cyclists, that's a fact, a situation you denied existed and claimed the suggestion was "risible".
The prioritising of motor traffic over all other considerations like facilities for pedestrians or cyclists, the stated aim of the mayor of our capital is to make things smoother (read faster) for motor vehicles. That's an erosion of the rights of vulnerable road users.
