@steeperthandeep to do that would need investment. Investors, including governments, just don't see where the return would be, so all we get is tinkering around the edges. The recent adverts advising motor drivers to leave a decent passing distance with cyclists just seems to have created outrage. Lots of keyboard warriors seem pretty comfortable with the idea of killing other humans because they once saw a bike go through a red light or a bike once gave them a scare on a shared use path.
