Every day dozens of Waymos are in close proximity to the people cleaning them and plugging them in, and they are maneuvering in tight spaces amongst other Waymos. That's not a peer reviewed study, but it seems to work.
The visual system can patch over tiny defects (see: blindspot) and visual field tests have not been part of standard yearly eye exams I've been to. And possible longer-term risks (say increased risk of cataracts) would be harder to conclusively show. And the sample size involved would skew heavily towards young healthy adults instead of people with pre-existing eye conditions.
I realize it's not easily possible to prove the negative, but when you're exposing the public the burden must be on the company to be transparent and rigorous. And from what I see it's difficult to even find certification documents for the lidars used in commercial self-driving vehicles, possibly because everything is proprietary and trade secret.
That's a possibility. Google appears to be contracting out depot work to car rental companies because a Waymo depot is basically a car rental lot. They need three shifts for each depot. So there's probably a couple hundred people who would otherwise be cleaning out rental cars working the depots. At some point injuries would get hard to sweep under the rug.
