Shooters choice @ 30 mph, might not be so easy for leo that typically targets my plate first. If you're on a bike with clip ons you'd probably be much lower than I usually am.

Also my rear sensors are not at the most rearward point of the bike, so the upward path being somewhat restricted may be the helmet acquisition issue on my install.
But it is a consideration, I'm thinking about where I might put a 3rd rear head for helmet coverage. I need an even smaller remote head that I can put on the helmet
