This is just going to turn into a complete shit show if it's implemented, most people out there are completely incapable of gauging distances of any length.
Cars already freak out about what to do when they encounter a bicycle on the road, this is just going to to make things worse. Then you just know entitled assholes on bicycles are gonna freak out on people if they think they didn't get their required 1 meter (but only when it's convenient to them). Maybe this could work if people weren't blind idiots, but if that were the case then we wouldn't be here having this discussion.
