• I always look behind Ed. I am 100% aware of what is behind me in terms of predictable solid objects. What I don't expect is a source of light coming from something that is not occupying that position in space at that moment. Say it takes 1 second to travel the distance between bike and projection and you are basing your movements on that, 1 second is a long time on a bike and it fucks your whole timing up.

    This is my initial thought after having only come across 2 and my instincts tell me they are dangerous. And I am also struggling to see who the light is aimed at. Not cars because what driver is looking 4 feet ahead of them at the road? Pedestrians are the only people I can see benefiting from this and the fuckers should just look up from their phones before they cross the road
