I have had several people notice the ContourHD on my helmet during my rides. Most encounters are positive, but two of them were negative and one was downright creepy.
The first incident was not captured on video because it happened after my ride and I had stopped recording. I was approached by a young man who claimed to be in the military. He asked if that was a camera I had on my helmet. When I said yes, he asked if it was recording. When I said no, he said that if it had been recording he would need my name, address, and phone number because he "could not be documented" because it would be hazardous to his safety. The gory details of that encounter are in this thread here on BF.
I am a female cyclist, and I can only imagine what that guy could have done to me had I been dumb enough to give him the info he wanted. Instead, I basically told him to go pound sand.
Yesterday I stopped to hook up my Dinotte to its battery pack, and a pedestrian took a little too much interest in the ContourHD and accused me of being paranoid. This time the camera was recording though.
The song snippets at the beginning and end of the video sum up my opinion of him!
Here's a more positive reaction from a runner who noticed the camera and liked it.
Have any of you ever had a negative or positive encounter with someone who noticed the camera on your bike or helmet? Any tips on good comebacks to the negative nellies out there?
