It's also true that illness and disability can come to any of us. Carol could have been a software developer who made a good bit of money before being unable to work anymore.

I recently had an obviously disturbed man come to the window of my Tesla asking for help. He did not specifically say money, but that's what he wanted. Long story short, he sees that the Tesla has identified a human standing next to the car, but the Tesla showed four people. The man asked how does the vehicle know there are people there, I told him that the Tesla has eight cameras around it. He then asked how does it know there were four people, I explained that the Tesla does not know there were four people, rather the Tesla has a hard time figuring out where something as small as a human is - it is designed to detect larger things like other vehicles. The man was obviously extremely affected, and walked away without another word.

Only later did I understand that the Tesla may have just confirmed what he had suspected all along - that there are in fact four people in the place where he is standing.
