It's funny how I was reading this thinking, "boy, people don't pay much attention." Then I read the comments about people backing in. Ah.. paradigm shift. The best way to work around this is just disable auto-open. The second best way is to pull into your garage instead of backing in - but I realize that's not always possible or desired.
Due to where the electrical power is, I back into my garage.
That said, I have never had a situation where the garage door was going to hit my car.
Seems to me you would have to be very careless, even backing up, to have this happen.
That said, for those that have run into this issue, try increasing the range. I increased mine from the default to about 40 feet.
This opens the garage for me as I approach.
If I somehow miss seeing that my garage door is open as I am appoaching my home, well, that just seems like I am not paying attention at all. I just don't see how you can miss an open garage door?
