>> should be REQUIRED on all bikes ridden on the road;
Please, no. I've been riding on the streets and roads for fifty years, I haven't been in physical contact with a hostile car in forty, and I don't need new rules to tell me what to do.
Nor do we need more barriers for new riders.
Consider that we require mirrors and turn signals on all cars...which is a good idea... but the use thereof appears to be plenty optional.
As far as drivers seeing my mirror? You give the average driver out there too much credit. I'm happy when they see ME.
