At this point, I'm just counting the days until a monthly subscription paid to the manufacturer eventually becomes required to even start the car.

You won't even need to own the car. Just pay $800 / mo indefinitely.

I have zero doubt that the car companies will do their best to make it effectively impossible to "own" your own car, in the same way you can no longer truly "buy" software.

I believe that’s called a lease.

Except you'll still have to outright buy the car first and pay a subscription to use it.

Literally happens right now for remote start
