Dear Mayor,
I've cycled the cycle superhighway twice in the last month. In this time I have had a chance to get a first-hand impression of the route. And for each time I've ridden it, of course, a cyclist has been killed.
I believe that the route has to be ridden to be understood, and accordingly, I invite you to join us (at a time that's convenient for you) in a small group of experienced cyclists on a route from the Olympic side to City Hall. Or vice versa, if you prefer. It is only by experiencing the junctions, the way all forms of traffic routinely ignore the blue lane markings, and how there is no effective enforcement aimed at keeping the lane open to cyclists, that you will ever fully understand its grave failings and the future fatalities which it is almost certain to cause. You may even discover that you will no longer wish to find your name associated with a cycle superhighway of this kind.
I hope you will be able to take up this invitation.
Yours,
