Still here, sort of
Lately I've tried to remember to ask riders I encounter if they look over their shoulder when about to change lanes. So many have said that they do it sometimes. Interesting that a common reason is laziness, especially in light of a discussion on a recent thread here that relying solely on mirrors is not safe. They go on to explain that they know it is the only safe technique to use. The MANYS/MSF course advocated that view. Do you do it?
