IMO no reason not to, with the more sophisticated GDOs we have today.

BTW, I think the electric eye thing is code, so that will not be a problem.

This is a very good idea.

what I hate is when you leave or go-to-bed and don't watch it go all the way down. Sometimes the photo-eye detects something or it feels too much resistance and for some reason doesn't close, it reverses and remains open.

I think this could be a bigger safety issue than it closing on someone. I live in the country, so if I sleep with my garage open all night the biggest risk is probably a skunk or snake getting in the garage--if I was in a different area, I'd have people in my house. Same for it being open when I leave for work. My wife's still sleeping.

Here's a partial solution to the problem mentioned by the commenter above: not knowing if a door has fully closed when you've entered the house. How about the door giving a Boing sound to confirm that it had closed? That wouldn't cost much. And if the buyer doesn't want it, he could turn it off.

If we had smart technology in every part of the house that stored info and communicated that info with all other parts of the house through a central computer, then maybe we would just need to call our garage door with our cell phone and ask if it is closed. But that hardware is maybe only for super rich people right now and at least 10 years from mass market.
