See that's a good use. I'm thinking of getting a "dashcam" style gopro or other camera^9^ for my bike (I might be able to get a free low end one through a law firm I consult with from time to time. I like free and at 15mph you aren't that blurry. Or maybe you are but for free I can try it and use it elsewhere like a chump if it sucks)
