I know of a very senior family friend living in one of the flyover states.

She doesnt drive following a car wreck. She had walk half a mile to wait out in the bitter rocky mountain cold at a bus stop to go to the Dr. Shes on social security. She told me she didnt have the money to take a cab, that is if she could even get a hold of one.

Then uber came along.

She learn to use uber on her own before even whatsapp.

Yea, I'd call it downright essential.
