Free SUC is not worth all that much. Over how many years would you need to calculate its value? Most charging of S/X owners will be done at home at low rates.
I just LOOOOOVE the idea of free unlimited SUC, but realistically it's worth only a few thousand Euros to me. Having the 17% more battery capacity, that's worth something. Look what people pay extra for Ludicrous. Just to momentarily get 200 Amperes more. Not going to be much more than a few minutes over the life of the car. Can you somehow earn that back doing drag races or picking up hotter ladies? Skipping superchargers in a longer range car, taking shorter to make it home, that's worth more, surely? Yet priced much lower.
