I live in Bristol where Motorcycles have been permitted in 98% of all Bus lanes in Bristol for the past ten years or so. Several exhaustive six-month trials were carried out before permission was granted to permit Motorcycles to use the Bus Lanes in the City of Bristol. Although there were originally objections from Cycling and Pedestrian groups, they were proven to be unfounded as the use of Motorcycles and Scooters in those lanes has actually improved safety for pedestrians and cyclists, and of course for Motorcyclists. By having those lanes used more frequently it slowly educates the pedestrians not to jay-walk, as they often do in front of quiet bicycles. The lanes can easily be shared by bicycles and Motorcycles as they can pass without hindering a cyclist. There's nothing more teriifying than being in a Bus Lane on a bicycle with a giant Bus right up your b***side trying to pass. Motorcycles don't do that. The use of Motorcycles in Bus Lanes also educates Car drivers not to zoom into the lane when it ends, without looking, as they often used to do and cut-up cyclists. It seem incredibly odd that the "Capital" of the UK is so far behind when it comes to permitting Motorcycles in Bus Lanes. You don't need to do any more Surveys or Trials. It has worked with 100% success in Bristol for the past ten years, and if it has worked there, you know jolly well it's gonna work in London.
