I just found this on the BBC website. I think it could be quite interesting if cyclists did have to take a test to ride on the road, and all adhered to taking Primary position in situations when that increases visibility and safety, and also to the bullet points under the photo of Boris. Most of the abuse I have had from car drivers is when I have taken Primary in such situations. Another thing Bikeability teaches is the pros and cons of cycling infrastructure (cycle lanes) and that they can make cycling more difficult and even more dangerous; riding off cycle tracks is another thing that has brought me abuse from motorists (even when they have been blocked by vehicles - local authority vehicles on one occasion).

Go for it I say. Have key elements of Bikeability built into a compulsory theory exam for the driving test as well (it is already taught to goods and passenger vehicle drivers under Safer Urban Driving, and is generally well received and often considered enlightening), we may all get along a bit better then.
