I am irrationally irritated by people telling me "be safe" when I'm moving on a bicycle. I know they mean well but they don't say it when I take the bus or get in a car, only when I'm on a bicycle.
Cycling in itself is absolutely safe, unless you're racing or doing mountain biking. But just moving around at low speed won't kill many people if they fall down. Even without a helmet.
What's dangerous when cycling is getting hit by a car, or a truck, or a van. And being told "be safe" shows just how much society won't discuss the real issue, and just wishes cyclists to "be safe". It's like thoughts and prayers.
Sorry for the rant.
