You wish. The situation is slowly improving but I had to wait 6 weeks for a car earlier this summer that was "in transit" (which I guess was to say it existed in the manufacturer's database someplace). This wasn't even a build to order vehicle. I suspect that would have been months.
I'm not sure where computational power enters into it. It's just that dealers want to mostly have cars on their lot which are acceptable to the greatest number of buyers who want/need a car right now which the model in hot pink isn't going to be for a lot of people.
An allegory.[1]
................
A random finds a fifty-dollar bill on the streets, exclaims, "Oh I'll go to a restaurant!" She gets there and is like "OK that chicken á la" squints "no not the French...the Adobe uh..." then waiter says "Adobado. That'll be $23.99." "Up front? Wait wai--" "Need the money to go buy the ingredients in the first place!"
.................
Yeah so they gotta mask that.
[1] Not claiming I'm any special anything, sticking to the true story I'm a slave of GOD, but that's irrelevant, anybody can say allegories. Maybe the parables are the ones that are for prophets only...maybe I'm thinking of that. Oh well. Best I can do. Used every other literary device by this point, in my attempt of elevating hn posts to an art form.
