Cycle campaigning

I think you may find quite a few of us are not pro segregation, and would rather the source of the problem was tackled instead. This can be done by better enforcement of traffic laws, speed limit reduction etc.

The loud emotive shouts of Danger Danger do not help encourage people to take up cycling.

sure, enforcement of traffic laws, and speed reduction, great - but eventually you run up against the laws of physics, and the limits of human attention.

assuming some driving errors, and collisions, will always happen (because no-one's perfect), even when you've reduced speeds to 20mph or so, kinetic energy is mv2, and, while you've got buses, coaches, delivery vehicles on the streets, you're going to have enough mass and energy in those collisions to kill an unprotected cyclist. so unless you want to shrink those buses down to bike size, you're going to need protected space on those roads if you want them usable safely by everyone who wants to ride a bike...

as for the shouts of 'danger, danger', one could argue that they're much less off-putting than the feeling of danger danger the first time a large vehicle cuts someone up, or passes too close...
