Self driving has an ongoing cost to Tesla for them to keep it updated and to improving upon its performance.

It’s only a subscription because it doesn’t make financial sense to purchase it outright for $15k up-front (with a 6% interest rate, you’d need to own the car for 102 months to pay less than paying for the FSD subscription for those 102 months, and it costs more per month in your loan than the subscription https://docs.google.com/spreadsheets/d/e/2PACX-1vSjfzhdfj0FU... )

Sure, though that highlights why someone would be interested in unlocking it (even without updates going forward). Personally I think I'd want mission-critical sw to be as current as possible, I can see someone arguing they should be able to run what's already sitting there on the computer in their car.

the software stack is different as far as I know. if you buy FSD and sign up for the beta program, you get a fairly massive software package downloaded. it is not instant and already on the device.

of all the things to hate about elon, tesla, and this whole concept of locking down features in a car, FSD really isn't one of them, as its just a software issue and its a totally separate package that isn't core to the operational capability of the car's components.

i dont have a settled opinion on software unlockable stuff. in general i think users should be able to hack it without repercussions. however, thinking about the concepts you present i had some hypotheticals. if tesla does all the self driving processing outside the car, it feels a little reasonable to pay them for their processing. but what if they just moved the heat seating processing out of the car (comparing the actual temperature to the desired temperature and modulating the power) ? that would seem unreasonable to me because the car is fully capable of doing it. So then what if tesla ships an intentionally terrible processor so that most data processing happens outside the car ? maybe it's reasonable again . ..

no point to this, just thinking out loud

Software lockable stuff sounds like in-app purchases. Should unlocking this content become legal ?
