So you hire more people to do the parking...? What's impossible there?
That's if we assume they don't just self-park.
The hard parts by far are actual production and getting in enough materials. If you can get in a thousand each of every single part, it's easy in comparison to get a thousand assembled cars back out.
Thinking just a little further, once the autonomy of the vehicle is good enough, there's no need to park the vehicle at all - you just tell it to start driving to a dealership or an owner's home.
There'd be some additional logistics to figure out how to recharge the vehicle as necessary on route, but that's a very different problem, and probably also amenable to automation.
its the space to store the cars, as well as the logistics of shipping them out - 14,000 cars comes out (optimistically) about 650 autoracks (railcars) per day - each one of those autoracks is 145 feet long. The scale of what is being discussed is near impossible, as it would mean an plant several orders of magnitude larger then any other ever constructed.. and I'm just focusing on the output - the logistics for the inputs for manufacturing are just as daunting.
