quote: How about not stepping out to cross the street. Try it sometime on a not too busy street that you're familiar with; close your eyes and see if you can hear a car coming and from how far away. I'll bet you can hear it well enough that you could cross safely based on what you do and don't hear. There are a lot of very valid complaints about this system, but it being worthless to blind people isn't one of them.
