For the 3rd day running I've bought the Thymes, I'm bothered by "cyclists: look out for parked cars, they might suddenly open their doors .... Look out for wing mirrors as well as through the back windscreen to see if anyone in the car might be about to open a door" (p6 of today's guide). So they don't want to encourage us to give 3ft clearance (might slow down the traffic flow).
The biggest threat to cyclists is the poor standard of some drivers, I've yet to see that mentioned, we need to get some of them off the road permanently & the rest to fear the possibility.
(same as I just posted to CTC forum).
