I've never heard of "expectancy value" in my life - it's definitely not a standard probability term.
Waymo cars go 11,000+ miles without driver intervention on average.
I would encourage doing actual research into this subject, rather than relying on your gut or the news articles you read.
Most self-driving is done in warm climates, in a circle. These companies are amassing thousands of empty miles on the same streets every day to impress people who don't know any better.
I lived on a branch of the main Google circuit, and often they were the only traffic for most of the day. Even saw three Google vehicles in a line, but two were more common.
What's the value of "self-driving" with no weather, traffic or route variation? PR and regulatory filing stats.
There was a driver, but I'm fairly certain that the drivers are not actively driving but are legally required to be there.
What? That's not at all what disengagements mean
How do you explain actual self-driving cars on the road? I find this attitude confusing as it seems to not jive with empirical reality.
I agree that we should focus on mass transit, but Waymo drives hundreds/thousands of miles without driver intervention.
