As a person who cycles, drives and walks, I want one simple rule that will make people more considerate on the roads. You're never going to be able to prevent idiots (cyclists running red lights, drink drives, etc) but as a general rule of thumb, here is a fairly simple suggestion that I think improves safety for everyone.
Change the burden of proof from innocent until proven guilty, to guilty until proven innocent, if you are the operator of the heavier vehicle (1) involved in a collision (2).
In other words, if you're a cyclist and you hit a pedestrian, you're guilty of dangerous driving unless you can prove it was the pedestrians fault. Same with a car hitting a motorbike. And all the way up the chain.
The idea behind this is to make it safer for the more vulnerable people (3) who use the roads, based on whatever method of propulsion you're currently using. If you're constantly on the lookout (as you should already be!) for dangers up ahead this should be relatively easy for most people to do.
