The Rearview Radar exists because of how terrible seeing behind you is on a bicycle. I ride a recumbent tricycle, and I simply have a mirror on the side which I can easily keep an eye on; due to my sitting position I conveniently behold the road before and behind me, unlike a road bike where it’s constant effort to do the same.

I really wish recumbent tricycles were more popular. The story of the exclusion of recumbents from races is rather sad.

Mainly because of bike snobbery: mirrors are seen as for dummies. [0]

I have a rearview mirror on my road/commuter bike that replaced the plug on the bar end and it works a treat.

I find that mirrors don’t work particularly well on bikes (I had one years ago but gave up on it), but the implementation works superbly on a trike, because the vehicle is wider, the rider’s position more conducive to using a mirror (not constantly craning your neck) and there’s actually a good place to mount it.
