Waymo may be currently safer than human drivers, but this right here is why I don't believe for a second they'll stay that way. People will complain it took to long to get somewhere because "stupid car was following all the rules!" and they'll be programmed to become more aggressive and dangerous (and due to regulatory capture they'll get away with this of course). I've already noticed this in San Francisco.
Look at when all the "No Kings" protests are happening: on the weekend. Because there is no way the vast majority of Americans can go on strike, because healthcare is tied to employment. This is why healthcare is never getting "fixed" in America--it's doing its job quite well.
I've taken BART and it's fine but expensive (there's an airport fee that's something like $8 per ticket each way). For groups/families I could see rideshare winning on both cost and convenience.
One of the houses across the street from me had its driveway dug up, all the way from the street to inside the garage, for what I first thought was for putting a bathroom or something in the downstairs level. When I walked past the old pipes they took out they were full of roots.
