If you’ve already seen this, my apologies. But I think it’s an interesting way to make sure you’ve got the evidence if you get hit by a car while on a ride, or just to deal with a driver harassing you. It’s intended to get the drop on hit-and-run drivers, which we’ve seen far too many of lately. Called the “Helmet of Justice,” it runs about $300.
I think its looks leave a lot to be desired, but it does have seven — seven! — video cameras. That ought to provide enough visual documentation.
