Given this is probably a pretty universal thing during the end of the year holidays, I'm sort of surprised Lucid didn't factor that into their production schedule. For all we know, they did. But my DA didn't ask me anything about potential issues with taking delivery in December. If anything, he was super-conservative about even suggesting I could get my car in December. He just basically said "Whatever you've been told in the past, let's go with that, and if I underpromise and over-deliver, so be it."
Personally, I'll take delivery any day. Christmas day would be fine with me. But I know that isn't the case for a lot of folks. I hope Lucid isn't going to hold up other people's deliveries over people who can't take their cars until January.
