Ignore all that stuff, and you're relying on luck for your safety.
Dude, sorry, but where I ride the cars are packed and mirrors are useless.
This is an example.
Maybe it's different for you but a mirror is nothing but an unwanted distraction for me.
This is old video and traffic is much worse now.
