I'm in LA, so I'm still skeptical about "safer". Granted, that's not a high bar, but I know who's accountable if an Uber/Lyft crashes.
As an bald, middle-aged man such risks are negligible for me, but I can see how some people might prefer a driverless vehicle.
If you're aware of a medical burden, you've done a pretty good job of avoiding the worst case scenario.
