This apparently is Ken Livingstone's latest big idea. All the better to then register every bike, and - he claims - to prevent cyclists jumping red lights and riding on the pavement. It reads to me more like another money raising scam, a new form of taxation. Having hammered the car owner, they start on the cyclist.
Would you believe I was cycling through the west end earlier this afternoon and I got waved over by a film crew from London Tonight, wanting to discuss this very issue!
I decided not to go into full Class War mode, but made several general points about Ken always playing to the gallery, there being far bigger issues for Londoners than the behaviour of cyclists, and that rather than using cyclists to raise revenue, he should cut his cloth better with the money he already has.
We will see at 6pm tonight if they use it!
