There's never been a perfectly-aligned falcon door, which is why no production cars have them. Sensors can be wonky, but hard to detect beyond making sure the open and close all the way.
You kind of blew your cover with the emails today, which was the right the to do, but you should show up with a Carhartt outfit, unshaven, real sloppy to catch them by surprise, and some fake glasses. Tell them you have terrible vision, but you're spotting some issues (if there are any), but like I said, your car looks as solid as Tesla can do these days.
