If there are "back" and/or "home" buttons that's a non-issue. And that's been my experience with oscilloscopes with this kind of interface.

A "home" is a reset. A "back" button won't solve the issue.

On a second thought, if the options are hierarchical, the sequence of clicks may not be cumbersome at all. Also, in a car the state can be something really easy to keep track of, like "the car is running", but even then, I'm not sure it's safe to rely on this.

mash "back" long enough and you'll get home... it might not be the best thing, but it works.
