No point worrying if that's how it should be
Why not? if it's wrong then it needs addressing, not ignoring. What you're saying there is that the motorcycling groups have given up on treating the disease and are just trying to lessen the symptoms, I don't believe that is true at all, but that's how your interpretation sounds.
It is absolutely right to teach people to be safe and look after themselves, but that doesn't have to mean ignoring other ways to improve safety.
"I'm vulnerable so it's up to everyone else, and the law had better catch up soon etc etc."
no no no, that's not what its about, it's about making the drivers realise you are vulnerable as well as making cyclist realise it and not putting themselves in danger, so that we all can get along and share the space.
The law does need to catch up with regards to appropriate justice when things go wrong, but the end goal is not to give cyclists carte blanch to say 'I'm vulnerable, so its your job to keep me safe'
It is not solely one groups responsibility, its the responsibility of all to keep safe and also make sure you're not causing a danger.
But then again how are cyclists supposed to learn this stuff? Would a few ad campaigns be enough?
no, but its a start, other options are to get it drummed into kids when they first learn to ride, and at school/bikeability etc, as well as trying to teach adults through community groups in conjunction with local authorities and businesses.
There is much that can be done, and much that should be done, cyclist training is very much one of those things, what is missing is focus and co-operation.
