I agree, I was almost mowed down by a Prius in a grocery store parking lot. I really think both drivers and pedestrians will have to learn better habits when in proximity with each other. I was walking back from breakfast this morning, when a mini-van driver, looking towards oncoming traffic, almost hit me. She emerged from a blind corner, due to hedges, and her minivan is already quiet. If I was on a bike, I wouldn't have stopped in time.
I really think it is going to be a re-education process for everyone, but I believe if the blind were able to buy a transponder, that would cause rolling vehicles around them to start beeping low tones, which beep faster based on proximity, then that should be sufficient.
