Yup they are really do just fit you perfectly those blinders.
if some ones illegally changes lanes then pulls in front of me accelerates then with no reason looks back and slows rapidly for no reason.. on a MUCH more agile vehicle and I hit my breaks but due to them being so close (by their choice) I cant break as fast as they do.. I will feel not in any way feel I was at fault.
Oh and have had 2 wheel vehicles been run off road by 4 wheeled ones but I never bought the “bikes & mobs are right” blinders.
Probably best to let a convoy of bikers just go on by, dropping speed slowly to encourage that to happen if they don’t get the hint. They will be happiest with their own, and no cage to be concerned about.
