Yeah that'd be nice, but it makes no economic sense for Tesla. They have a backlog running all the way to 2023 for making these cars. They have finite factory capacity. They can either sell one at $48k with a few options to someone who expressed interest a year ago, or make the exact same car and sell it for $58k right here, right now.
We're lucky that they have mostly honored older reservations at original prices. I don't think they are obligated to do anything more than deliver what was ordered at the original price. It's nice that they are allowing fairly recent orders to be adjusted a bit... But to pretend they're doing that to make more profit? Nah
