Not just for blind people (Score 1)

I just learned that around 800 pedestrians per year are hit in San Francisco alone. Forgetting jokes about bums and jaywalkers, I'm guessing a significant percentage of those people were doing exactly what they were supposed to and the car just didn't stop for the red light, or didn't yield, or they didn't see that car coming from behind in the six-way intersection. If there were no audio cues I am sure these unfortunate rates would just go up. If you're thinking in binary and believe we ONLY need one sense (sight) to protect us from accidents... give me some of what you're smoking, please...
