I have the advantage of my gender and I’ve used it.
If there is a more nonthreatening human being on a bike, I’d be surprised so I can say things a bit more boldly and not get a defensive reaction. How upset can you get at a grinning woman wearing a ridiculous rhinestone helmet?
“Hey! I almost didn’t see you. I bet the cars really can’t see you. If you’d like, stick closer to me and my mega death lights.”
I’m honestly concerned for their safety and the last thing I want to do is scold them, I get enough practice at home with my children. But I am giving them an honest reaction, I can’t see them, and I am offering assistance that most big guys on bikes would prefer not to ever take. The one woman I spoke to admitted she was out later than she thought and she rode with me until our paths diverged.
BTW, I ordered a set of battery operated Christmas lights for my bike, just to make things festive.
