I haven't tried backing in yet to test it out. Summoning would take car of any issues, but since we have fine access to car as is, I don't know how often we'll use it. I think the garage door opener is so low in my garage that it would interfere with one door opening. If it was centered on the garage door I don't think it would be a problem, but since it's slightly offest to the right of the garage as you enter it, it will probably stop the door from fully opening. I'll test it out soon and see. Still on 7.0 so don't have summon feature yet.
