Given all of threads on garage re-works / clearance issues and my own personal experience - it seems like there is a relatively simple solution that would be somewhat consistent with the way horizontal clearance specifications work. Why not let users define the ceiling clearance height in inches for a given location. This would allow us to have a consistent door opening experience in the home garage (whether or not the garage door is open). In my case - this would allow me to resolve the issue of rails and garage door opener that are not detected by the sensor when my garage door is closed. Potentially, Tesla could augment this with height constraints in other locations frequented by owners (super chargers in indoor locations).
