I don't really understand what "FSD" means. Anyway, I hope that the Model 3 or some future model is eventually going to provide a well made electric car that allows me to eventually have one I can put a kayak on a rack (without "wing doors"), could fit a lot inside, such as how a Prius wagon can fit a bicycle thrown in the back if you once in a while have to drive the bike to a bike shop to be fixed, and is not a luxury car that gets some huge 150 mph type power. But I do like great nav systems and adaptive cruise control, all wheel drive, many miles able to be driven on a charge. I wish there would be more ways to charge it without having to own a house. I have been renting my place instead. I don't like the impression I am driving a luxury car because it sets me up to be insulted and resented by people who think I'm engaging in conspicuous consumption -- I have to deal with people like that daily and I don't like showing off. I am not interested in snob appeal. It's fine for Tesla to have a model or two that are luxury cars if I can get one that isn't luxury but is part of the new future electronically and is extremely reliable. I love the display screen on the Tesla I test drove too.
I'm kind of afraid that the Model S/X could turn into a very generic model car. Choice A or B and no real customizing. Ultimately while that may be favorable to push more cars out of the production line faster, I don't think it does anything for making the S/X special and unique, which in part from the electronics and battery (agreeably a big part of the car) is what keeps the car in the luxury class IMO. I would have thought they wanted to retain the uniqueness of their two larger margin vehicles and don't see this shift in production line minimization as being a necessity. Don't they have separate lines and work crews for each vehicle? Why sacrifice the S/X for mass producing the Model 3? If we ever get to FSD in cars in general, and you don't even own a car but call one, who the heck cares I guess what kind of car you are riding in.
