then by all intents and purposes you don't need HW3 at all, and returning the car for something that has no effect on its functionality is irrational.
But hey, there's no law forcing you to be rational. Return it if you can and if you want to.
If you had no delivery issues other than the HW revision I think you're not only irrational but also doing yourself a disservice, since you never know another car like it delivered later might have more cosmetic defects, but that's just my private opinion.
Geez, I have HW2.5 and I have ordered FSD. I'm just a bit miffed that the car is going to have to be torn apart to install HW3, but I don't return a car just because I'm a bit miffed.
