However, this isn't a bicycle problem: it's an urban planning problem. If you design for cars (multi-lane high-speed roads), this is what you get. Unfortunately, riders and pedestrians will suffer for now.

Hint: Mount a retractable side flag to your bicycle and hang a sharp, metal object at the end where the reflector is. Leave it hanging on a long enough string (10-15cm) so as to allow it to move around easily. That should keep car drivers away, at least those who appreciate the paintwork on their cars.
