There is another way to set it to a certain height for a location (ie garage) - by pressing (hold it until desired height) on the open FWD button on the door, or from Controls.Yes you can change the height from auto to low so it only opens half way. That should reduce the risk of hitting the ceiling. But I am not sure about cars parking next. I believe the trajectory of the door opening might be different when it detects car parking next, especially in tight space.
This height/location is confirmed by a long beep. See attached.
