alt Hacker NewsI use a Garmin edge bike computer and a Garmin tail light with lidar that shows cars as they come up from behind on you on the computer screen and give audio alert as well.
That works well enough for most road riding. I wonder if having a reverse view mapped onto my glasses would be an improvement or take away from my focus.

So about the lidar: what does that actually do for you? Or I should say, what do you do in response to it? Do you yield more road space if it tells you a car is approaching? I've been trying to understand what good such an alert actually does for an otherwise attentive rider.

I use a [mirror](https://takealookactive.com/), it adds so much more confidence and safety that I'll refuse to ride without it. Helps me make left turns, avoid aggressive cars, and make sure I'm not dropping my friends. No fancy electronics, no battery to charge, and it's inexpensive to replace.
