Just yesterday, walking in the inner sunset neighborhood of SF, I saw an old lady in a 1980s Volvo come to a 4-way stop. She looked really old, as in probably even 90+. She wasn't sure about the rules of the stop sign: she came to the stop and was hesitating to go. Other cars were waiting for her and some of them started just going through, creating a very dangerous situation. Eventually she mustered the courage to just make her turn. That made me think: her life would be so much easier if she didn't have to drive at all to go run her errands. She was creating an unsafe situation for everyone, not just herself.
The City (SF) has a fleet of transport vehicles that transport Seniors (old folks) around town. It would be much more cost effective to just have a bunch of Waymos available to Seniors.
