About the only way to enhance rearward awareness is to either have mirrors or radar or be regularly looking. In such situations, this sort of radar seems to fill a void that might otherwise leave a person fairly surprised and without options. (Have used mirrors. In my experience they work well enough, but they do take attention away from what's up ahead and they do require frequent checking. Whereas a radar would do the looking for the rider.)
I suspect that many people in similar urban areas have to contend with higher noise levels that'll drown out much of an approaching vehicle's noise.
I'm sorry, but I have to politely disagree, I've been riding on city streets for over 45 years in places like Los Angeles,
San Francisco, Detroit and Chicago, just to name a few, and never wish I had a mirror or a radar. People have been riding for years without either, like I said before, if someone is going to hit you that radar isn't going to help the least bit, they are going to hit you. I just don't think it's necessary to have that stuff; but you do you, and I'll do me.
