> There is also a different kind of increased safety. There is no driver. No weird conversations about slaughtering goats, no sexual advances. No worrying that your driver is going to assault you or attempt to kidnap you.
There are also new risks that weren't possible before. A software error can send you into oncoming traffic. Hackers can gain control of your vehicle either directly/remotely or by cleverly designed signage placed on the roadside. A disgruntled waymo contractor in the Philippines can remote drive you into a crowd of people. A flashing stoplight can leave you stranded at an intersection. The car may not see or react appropriately any number of uncommon hazards that human drivers would recognize and avoid. Only a relatively small number of these cars have been on the road, in limited conditions, and only for a small number years. There will be failures and risks we haven't even imagined yet.
Frequency matters.
One of these sets of risk is mostly theoretical (aside from the large scale stoplight outage), one of them is happening often enough that anyone who takes rideshare repeatedly will have a story.
If we limit ourselves to risks that have actually manifested, not hypothetical risks, I'd rather risk getting stuck at an intersection if there is a city wide power outage than deal with the weird conversations I've had on rideshares (not even counting the countless drivers who demonstrated that it is possible to drive a car without crashing for the duration of one rideshare ride without taking your eyes off the phone for more than a few seconds at a time).
