I understand the idea, but it falls short in the convincing department. Just another thing to deal with before a ride, which is how most of us try to decompress. The perceived margin of safety is anecdotal.
What jumps out to me first is that it's another thing that I'd have to charge. I have a hard enough time keeping my Bluetooth headset charged before rides. @ $170 it's not cheap, but can you put a price on safety? I kind of feel the same way about the A* Tech-air vests. I don't ride often at night so I'm not sure how much more visibility this would provide during the day. I just wonder how bright it is. Definitely interesting!
