Your original reply stated that “including heated seats and making you pay once to access it is fair game” is what prompted my reply. Users shouldn’t be paying for it if it comes with the product, disabled or not.
I have no qualms about subscriptions for FSD due to continuing developments and improvements, and the fact that it requires a service running AI/ML models to operate. However the drastic subscription cost changes over 3 years raises an eyebrow. From $5000 in 2019 to $15000 in 2022 is quite a drastic change. They certainly have the right to price how they want, but definitely an insane pricing model.
