"Backorder" meant "Idiots with a couple hundred dollars". "Orders" were a whole $100 fully refundable deposit. It was a complete non-commitment, and I know a ton of people who literally bought them solely to resell their "spot in line".
I knew a dude who put in an order for 5, just to ensure he could sell his "spots on the list". Dude was a service tech that couldn't afford even the fake $40k price, let alone the current $100k price. I've seen tons of stories like his as well, so there's a 0% chance even 20% of those are actually converting to sales.
