You hope the car relies on continuous signal from the phone to proceed. It's certainly possible that the phone freezes in a way that the "keep going" signal continues to be sent, but it's probably not the more likely failure mode. Definitely a good thing to be concerned about!

I may be just a bad developer but my first thought when I see or build a new feature for anything is "how could this go wrong, and who will it kill if it does?" Thankfully, I don't make self driving vehicles, so the second question is usually at worst a handful.

It's not a bad mindset to have.
