Patpur,

I like your idea. I wish you would patent these and make millions so that these become common in parking lots and socially acceptable. I think it is a really good idea, I just wouldn't want to be the only one wearing these. If these became popular no one would have to be careful. People would just throw the doors open. Imagine the poor souls that didn't have these then? They would have to get them! Everyone would have to have them.
