I would not be surprised one bit if customers don't see deliveries till December. My guess is between Thanksgiving and Christmas as a "we met the end of the year promise". I do believe they were getting close to deliveries but my guesstimate is that between the ride quality (mostly road noise) issues that multiple people point out during the factory trials and soon after, AND the main in-car user interface software needing final tuning they will most likely hold off deliveries till those items are possibly (hopefully) addressed. I feel like even the factory road tests were in cars that had limited touchscreen functionality and I didn't see any videos that walk you thru the various features the screens provide. Even the test drivers seemed like they were instructed (and diligently watched by the passenger seat lucid employee) so as to make sure they didn't touch any of the screens beyond what was agreed upon.
Just my observations and 'reading in between lines'. Hopefully I am proved wrong and we get a delivery update sooner but I am not holding my breath!
