Just look at what happened when they tried that during COVID. Elon is a loud idiot who’ll screech about how he’s being oppressed, and unfortunately still has a lot of equally loud idiots as followers who will gladly harass the underpaid government employees who actually have to enforce the shutdown on his behalf.
I assume you’re probably thinking of all the “pre orders” they supposedly had. However, the take rate of zero-commitment “pre-orders” from 5 years ago for a product that was 50% cheaper with significantly better specs has been pretty low, especially given that far better vehicles have become available since it was announced.
