I wouldn't want the responsibility either

I need to get across the street so I walk over to the crosswalk and push the little walking man button.  It begins beeping to let me know that this is an audible cross walk.  When the flashing lights in the street turn on, a little voice speaks up to say "Proceed with caution, cross traffic may not stop."  

the "Shaft" of public service signals

At first I'm annoyed thinking the American's with Disabilities Act is wasting my tax dollars and won't let me cross the street in peace; then I start to think about the poor blind man who this is designed for.  Let me repeat the words of advice doled out by this electronic voice of hope, "Proceed with caution, cross traffic may not stop."  If I'm a blind guy I'm thinking "Oh good, I was afraid they were going to let me know when it was safe to cross."  The blind man already knows the cross traffic may not stop, I assume he's been dealing with that his whole life.  

Naturally he gets hit by a car and takes his case up against the city for providing an unsafe crossing environment for the disabled.  But the city has a lock-tight defense.  "Look, we told you the traffic may not stop."  They weren't taking any responsibility in the first place.  Next week, they're putting up release of liability wavers you have to sign before you cross the street.
