How to make the roads safer?

I think all cyclists (and all car drivers) should do motorcycle CBT for 2 reasons:

1. The standard of training is superb and is all about road safety and traffic awareness, but is also about riding assertively.
   
2. Everyone can benefit from seeing how the other half lives. When car drivers go out on motorbikes they realise how scary and dangerous it is. When cyclists do they realise just how passive and dangerous their riding has been up till then.
