My model X will not autopark in my garage because it is detecting a 1/4 inch gap between the garage floor and driveway height, I asked about it during a recent visit to the new Savannah location. They told me their garage had same problem so they shaved off the difference. However, if I do same I will have a drainage problem . Lead technician told me to "sit tight " for now. Tesla was aware of problem and will issue a software update to address. Looking forward to update.
