I don't get it.
When I ride down a road with drivers who are observant and thoughtful, and give me space my riding is hassle-free and pretty safe.
It's only when I get people tailgating, close passing, pulling out without looking, leaning on horns etc that it feels dangerous. As it happens I see the same behaviour when I drive.
In my mind if one driver (car, van, lorry whatever) can drive carefully around me, so can all of them
So the problem is clearly one of behaviour rather than infrastructure and I can't see how changing the road layout enforces good practice and the law...
Surely more Police just watching (which has it's own impact on bad behaviour), or pulling people over for a bollocking or an arrest etc would be a better long term solution.
Any segregated infrastructure still has to rejoin the main traffic at some point which creates concentrations of cycle flow into traffic and greater danger.
Is there any evidence that infrastructure solves the problem? Or is it just politically easier?
