I totally understand your point and it's definitely possible that the future software updates will take forever to come out and/or potentially cost extra $. It's too early to say at this point on. On the other side of the coin, I think the Tesla and Lucid's sales points are (or should be) two different things. With Tesla you bought 'Full-Self Driving' which was marketed as that, and I think a lot of customers (rightfully so) feel cheated because the software, to this day, still does not 'Fully self drive' you around. On the other hand -- Lucid never promised nor advertised such thing. Paying for DDP buys you the hardware that is capable for future autonomy via software releases. I think it all comes down to having proper expectations.
