I get what you are saying. But Lucid tried that with the GT, and it left many customers confused and frustrated to have their VINs assigned and then be left with zero progress indicators for months after until delivery was scheduled.
I think what Lucid is trying to avoid here is false hope. And more accusations of "failed promises."
Many people on the forum have argued Lucid needs more transparency into the process. I somewhat agree. But that process often involves days or weeks of literally nothing happening. A car can roll off the production line, then sit for weeks waiting for the PDI staff to get to it. Then wait more weeks for a carrier to take it to the delivery site. All that waiting is a perfectly natural part of the process, but to a customer with no inside knowledge of how cars are manufactured, it can easily be a source of confusion and frustration. "Why aren't you working on my car every single day?!"
That leads to more angry contact with customer service. Which adds to overhead.
The same goes for the order of reservations, plus finalizations, plus batching. Yes, it sucks that someone who wants Mojave and reserved two years ahead of me won't get their car until months after me. But they have to start with some spec. And they have to batch as many similar cars together as possible in order to deliver as many cars as possible as quickly as possible.
If it weren't for forums like this one tracking orders, most folks would have no idea some who reserved later are getting their cars sooner.
I am convinced almost all of us with hopes of a delivery this year probably have a VIN assigned already internally. Many of those cars are probably already built. But even just getting the handful of DAs on staff to email each of us to inform us of that VIN would likely take many days. (It's still a manual process.) And that's if they were doing nothing but emailing VINs to people and asking to confirm address/phone and other details.
Inevitably, some would take that VIN, apply for financing and insurance, then lose their quote when the car doesn't arrive within 30 days. Leading to more anger and frustration.
If you knew your VIN, would that give you any more knowledge about when your car will actually be delivered? Not really.
My DA still avoided guaranteeing my car will be delivered this year, even after giving me the VIN today. I think it's extremely likely I'll have it in a week or two, but there are still too many variables to sort out between now and then to be 100% sure.
I'm convinced they would not give that number out at all until they were ready for delivery if we didn't need it for insurance and/or financing.
Whatever the thought process, I think Lucid is trying to learn from the past and make corrections in the way they hand out info to customers for this Touring run. Maybe in the end they will decide they over corrected and try and find a better time to give out VINs. I don't know. It's still definitely a flawed system.
