Earlier quoted context omitted.
The whole car metaphor is a bit unfortunate. Most people who want to drive securely from A to B would be pretty freaked out by a bunch of strangers quietly upgrading their car's brakes in the middle of the night. And they would definitely be pissed off if their car suddenly refused to accelerate beyond 25 mph on a clear, straight, empty stretch of dry road in broad daylight just because the speed limit happens to be…
This argument can be also made positive. Imagine a new update (to be on your example, the new brakes) made the car safer and the saved your life because an accident could be avoided entirely. Otherwise you would be dead. It's not only negative... Btw. when thinking of Tesla cars.. they auto update their software remotely ;)
To illustrate my point in terms of your analogy, if people could get free upgrades for their brakes that make the car safer, I like to think that they would still prefer to be given control over it, because they see it as "my car" and not "my car, but with brakes licensed from someone else". And I also like to think that they would object to arbitrary changes to the insides of their car with vague explanations of how the new insides are better.
