I don’t know if they are more but my reaction certainly has changed over the years. Like just now, our canal MUP crosses a pretty small street. I stopped and did nothing even as a guy in a huge SUV was wiggling his fingers like to tell me to go. First of all drivers really don’t understand that with all their tinted windows it’s not easy to see, and second if I do go and he runs me over then I can’t prove what he did. So I just looked straight ahead, not acknowledging anything. I’ve been knocked down while walking along the road in front if my house and I know it really hurts. And I know on a bike that I will lose or just be dead. And in the courtroom this guy will deny everything. And get away with it. So no, I don’t respond to these “courtesy” signals.
