Not stopped, but today I was riding in a neighboring town. Just back roads and pretty low speeds, so I wasn't wearing earplugs. But I'm on a busy four lane surface street with cars all around. I'm going through an intersection and hear some guy yelling a question at me. I think he may have been hanging out the window of a van that was a car behind me and in the next lane over - not really sure. I think he was saying WHAT IS THAT!!? Maybe he was asking what kind of bike I was on? Not really sure. I'm in a full face helmet in moving traffic. I just ignored him. People are odd.
