Since the question was VALUE, not how many dollars did you save I still come down on the side of FSD. You may not think it's replacing your chauffeur, but it IS still a second set of eyes on your driving. I feel a LOT more confident having the car keep the frick away from sus cars and windblown trucks as I scoot down the highway. Sure the safety modes of the car are fine, but I would MUCH prefer that it come slowly to a stop at a sign that I didn't notice than have it scream at me to frickin' stop already.
There is value in that.
Sure you can save some dollars on charging for free, but those cars that have that feature also charge really slow (mostly). So you are DOOMING yourself to slow charging even when you are in a hurry and just wanna make it to the basketball game in Colorado on time. If you have the time, hit up one of those slow CCS chargers that are free or cheaper than Supercharging, but when you need it you have 250kW speed to get to your destination in a hurry.
VALUE is always relative "to whom". My wife has enhanced autopilot on her car, but she keeps it disabled. If she had FSD, she would have kept it disabled too. Value to her, $0. She has only used free supercharging a handful of times, but that is still value to her than FSD would have been. The fast charging you are describing only happens in some very specific scenarios, low SoC, hot battery. If a few minutes difference in refueling time is going to DOOM you, you need to be driving an ICE car - time saving of gasoline refuel vs 250KW is much higher than the difference between supercharging a car which can peak at 250KW (during a short window of time and conditions) vs. a car which peaks at 150KW. You also may need to detour to reach 250KW capable superchargers, as some, for example the Tesla urban superchargers, max out at 75KW. I have one of those urban superchargers near my house, 75KW is the max, but when they are all full, it drops even lower.
Now, if you are a YouTuber and make money making FSD videos, of course FSD is much more valuable to you than FUSC. It is obvious from your posts, FSD is much more valuable to you, but given the poll results as of right now, you are in the minority.
PS> Most EA stations have 350KW capable CCS. Not sure what a Tesla can pull from them via the adapter, but I suspect 175KW since Teslas use 400V batteries.
