As regards whether getting the FSD option is worthwhile or not. I'm not in the camp that compares it to Bitcoin. (Or, rather, implies that you'll give Tesla money for which you'll get no return: i.e., it's a scam.)
- Tesla has promised that it's going to deliver autonomous vehicles. They've got tons of people working on it (what, 2000 on "recognition"?). They've got this Dojo complex coming on line, which will purportedly up the training speeds of the neural networks built into the computer. The cars themselves have duplex hardware (duplex high voltage connections, duplex processors, etc.) that are meant to safely bring the car to a halt in case of a failure, not something one would see if they weren't going to do full autonomous route. So, they're serious.
- Musk has personally said that the closer they get to the Full Deal, the more they're going to charge for FSD. And that's been happening. Back when I got a M3 in 2018, it was $2k. Now it's $10k and rising.
- Once the full deal appears, there's serious talk on Tesla's side about charging a lot more for the cars, period. Why sell a car for cheaps, when they can put the Full Deal FSD in it and use it for a taxi? By the by: I'm not making this up, this came out on Autonomy Day. The idea is that when you've got a car like this, you can send it on its way, daily, and let it do its Uber thing and make money for you.
- I dunno how it is in the U.K., but in the U.S. it's not uncommon for people to pay a builder to put up a house on what looks like a field, covered with weeds. One gets a discount for doing that, rather than waiting for the house to be complete and move-in ready. Before doing so, it's recommended that a potential buyer do some due diligence: Make sure that the builder is legit, there's bonds posted, contracts carefully gone over by lawyers, ask previous customers their experiences, and so on. (Yes, I've actually done this.. and am currently sitting in a house built and bought that way.) The way I figure, FSD is really no different. No, it's not ready, yet, but one can get it for a discount now.
- The real question is trust. Many people, especially people who Really don't want Tesla to succeed, throw up a lot of smoke about Tesla. And Musk, in particular. Funny talking guy who will never win any contests for ease of public speaking. On the other hand: This is a guy whose company is landing rockets and reusing them, something that a lot of nay-sayers kept on repeatedly saying couldn't be done. These are the same people who are currently watching their pockets get drained. My observation is that Musk tends to deliver. Admittedly on Elon time, but he gets there.
As you might imagine, I did put my money where my mouth is. Not right off, but when it was passing through $5k. The 2018 M3 got the G3 computer upgrade; it's got the auto-park (which does work); it's got Summon, which the SO and I played with in an empty parking lot shortly after getting the tool, and not since then; and we've been driving all over the eastern half of the US with the auto-nav/auto-steer/TACC on. It works. Still buggy sometimes (now and then, not too often, we get the infamous phantom braking, but not the emergency braking some have intimated). And, in the U.S., it does a decent job on 4 lane major highways with stop lights; it'll come to a stop on a red light, and then either follow another car through on the green or, with a flick of the shift lever, go through on its own.
Not perfect, of course: Reminds me of a 17-year-old driving. And it makes sense to take over when things look dicey. But it makes driving between New Jersey and Boston, something I do on a regular basis, a lot less stressful. (Not sleeping, mind you, just less stress.)
