It is very much for me as a prospective buyer as a measure of trust with the company. I don't mind being sold some sizzle but I don't want to sold a bill of goods.
My impression when hearing about FSD is that the car could soon go off in the mall, drop me off at the door, find a parking space and return to get met on summon. I thought it could drive highways no trouble and do some limited city driving like inching forward in traffic jams. My wife and I would arrive home at the airport and I'd say to her: "one day rather than getting an Uber, we'll just come have the Tesla pick us up!"
It seems to take a fair amount of research to realize that this stuff aint here, aint coming this year and likely not in the next 2-3 years afterwards. Autonomy day notwithstanding, which I did watch live.
So ultimately when you buy FSD now, the only thing you are really doing is funding R&D and protecting yourself from price increases down the line that Elon's going to cram down should he actually get FSD to work. Rather than constantly have Elon threaten us that it's going to cost more any minute now, he ought to be thanking the bejesus out of me for financing development. (Hey dude, where's my swag?)
I'm not saying that I won't buy FSD now (it's currently in the order) but whereas I used to believe would be growing leaps and bounds in functionality quarter by quarter but I now believe that there's a 50/50 chance I'm not buying much of anything. I guess the bottom line is it's diminished the trust factor regarding both Tesla and Elon before I even make the purchase.
At least I downloaded the user's manual to understand what it really does now.
I wonder about all the poor suckers that buy without doing research like this.
