Collisions are inevitable unless roads are designed to prevent them. Roads, bicycle paths, and footpaths (and railroads and canals and etc) need to be designed in such a way that traveling is safe and economic for ALL traffic participants. Not just one particular type of vehicle. So far this policy only exists in a few countries in the world, but the concepts are slowly spreading elsewhere. Never quickly enough of course!
