Nearly all humans depend on powered infrastructure outside their car to drive it. You're describing a shortcoming of all 21st century navigation.

I think the 100 or so miles I can generally drive in my car while it still has gas is different from my car just stopping suddenly because of a power outage.

Horse manure. If the power goes out, I can still drive. Including navigating intersections. Same for my cell phone.

Tell that to all of the humans who were capable of driving, but blocked by a fake autonomous car that froze in the middle of the road.
