It can't hurt Tesla. It can hurt someone who can't afford $7,000 without getting something of real value for it. But why stop at $7,000? Why not give then $100,000? Heck, why not give them $1,000,000? That might get them to FSD even sooner. It would certainly show them that you're serious.
There are no safe bets. And Tesla has arbitrarily chosen to cripple itself by insisting on using cameras alone, and only eight of those.
You don't have FSD. You have EAP, which Tesla in its wisdom decided to quit selling by itself, and make you pay for FSD (which does not exist, and won't for at least several years) if you want EAP.
I bought EAP with mine and I think it's the best thing since sliced bread. I think Tesla might end up being the first with FSD, but I'm not going to lock myself in by buying it before it exists. Tesla has plenty of money of mine, which I was happy to give them because they gave me something in return: A car, some equity in the company, some interest-paying bonds, and then another car. All good sound purchases. And they can have some more money of mine when they offer something of value in return. FSD on a car with 8 cameras and no lidar is a pig in a poke.
Unfortunately, Tesla has chosen to obfuscate the matter by changing the definition of FSD. For someone who has EAP, buying FSD is paying for absolutely nothing but a promise. For someone buying a car today, you have to pay for the worthless promise of a self-driving car "some day" if you want to get the features of EAP. When I bought mine, you had to buy EAP just to get the basic AP. Now the basic AP comes in all Teslas but you can't buy EAP without paying for FSD.
It's just plain dishonest to say that anything short of Level 5 is Full Self Driving, and Tesla has as good as admitted that that is years away, yet they're still selling the promise, and requiring you to buy that promise if you want EAP.
