@Lucken and
@hydbob Unless it changed in the past week or so, Scottsdale still has the policy where you need to have a confirmed reservation to test drive. While that made sense in early mid-December when they first got the car, it probably makes less sense in mid-January. Presumably, any AGT confirmed reservation holder would have had the opportunity to do a test drive. I guess if they are continuing to send out invitations to confirm every two weeks, then maybe I could understand a little bit more, but I really don't get the sense that they have an inundation of reservation requests. It's steady but not overwhelming, I think.
Having said that, if I were Lucid, I'd look at my reservation data and try to determine an approach that opens it up more without overwhelming the shop. While the test drive is around 15-20 minutes, the whole process takes about an hour, so you likely need some protocol (e.g. type of car reserved, order placed, etc) to make it more manageable until you have better information and can adjust again. But for now, I would tend to agree that there should be a way to open it up a bit more.
As an aside, it was interesting to find out that though it's not open as an official service center, the Scottsdale service center is being used to prep DEs for deliveries to 6 states I believe.
