So, when I was working a brain injury unit in Balt., I had a younger pt. who had been attacked hit in the head. His uncle visited him often.
One day, the uncle was complaining about the "ko ko" bird sound the went of every time the traffic light changed. Apparently it was right outside his downtown apt. window.
He asked "What the heck do they hook that up for anyway, its goofy if you ask me?"
I told him "Its for blind people so they know when the light is green/red."
He responded "WHAT THE HELL ARE BLIND PEOPLE DRIVING FOR ANYWAY?"
I couldnt resist, I told him the new hybrid cars have "autopilot".
His response: "We could eliminate drunk driving with that. If you had a few, turn on the AP and let it take over. They shouldnt keep things like that for only the handicapped and the rich. I'm going to write a letter to my congressman"
I told him not to mention me in the letter, it was against my religious beliefs to deal with the govt. Next day, he said he wrote the letter but didnt mention me and asked me "Are you satanic? Thats why you hide from the govt."
I stopped there, never told him the whole truth, but didnt egg him on anymore either.
