I think the car analogy isn't that bad. New classes of security issues get discovered over time. Development processes which are considered "state of the art" at one point can become unacceptable 10 years down the road.

A decade in software engineering is a significant amount of time!

For the car analogy, what will happen when self-driving cars become the norm and the contained software becomes so important?

I'm going to be annoyed if my car becomes useless after 10 years because they dont have to patch it after that period. On the other hand though, can we realistically enforce lifetime guarantees? What is a car company goes out of business?

Pretty sure the endgame for self-driving cars is pretty much nobody owning cars anymore. It will become too convenient and cheap to rent one instead (possibly not in rural areas, not sure about that). Kind of like how very few people in big cities bother with owning cars.
