Failure in the mobile assembly line is what the article mentions but is kind of irrelevant if you're still just selling pizzas to people. No one really cares about buying pizza from this unknown company so they have no product market fit. imo cutting minimum wage humans out of the loop will not yield a big enough profit weighed against the machine and vehicle maintenance costs combined with the skilled labor costs to deal with them.

So maybe ~10x cheaper? I wonder what is the cost of ingredients for a $20 pizza. $2 seems low.

Flour costs less than 50 cents, sauce maybe 25 cents, probably at least $1-2 for cheap wholesale cheese, plus toppings.

Hot pizza ovens aren't free to buy or operate. It's hotter than a normal kitchen oven, and energy isn't free.

Not just cut the human out, but I must also assume having it truck based cuts out building rental/ownership costs also

It didn't truly cut most humans out of the loop. The one near my house still had 2 delivery drivers because the pizza vehicle was permanently parked down a side street. They were only saving the cost of the third, pizza cooking employee and the capital expenses of the robot truck probably outweighed that single minimum wage several times over.

Their MVP was simply missing any key differentiators from established competitors except for the terrible pricing.
