On the subject of what's too close... Doesn't the Highway Code say "Give a ccyclist as much room as a small car"? I've always felt that was open to interpretation - as much room as you would leave when overtaking a small car, or as much room as if they were a small car? I think the two are not exactly the same - assuming a cyclist is the width of an old Mini parked at the side of the road and passing at the point represented by the side of that Mini is still quite close, esp if the cyclist is already in primary. Passing a cyclist as if they were a Mini driving down the road means properly crossing to the other lane/side of the road. No wonder the divvy ones can't work it out.
No legislation is any good without detection and enforcement. Presumably that's why people get uppity about speed cameras, because they allow the automation of both, and hence a better result. I hear that they are also planning to cut speed limits in a lot of places - introduce more 20 zones, and cut some rural roads to 50. Apparently motoring organisations are saying "well, that's sort of ok, but driver training is the key". So why is driver training apparently so shoot? Although I gather they intend to tackle that too, and in ways I think might be good - like a pre-licence training at school scheme. Trouble is, those kids who opt to take it are a self selecting group - they see the merit in good training. Those who don't care, still don't care....
