I’ve taken a few dozen Waymo rides, but it doesn’t matger because this is not something you can really test as a person. The entire issue is whether you have, say, 7 or 9 nines of reliability (e.g., 10x or 0.1x times more dangerous than a human), and you can’t extrapolate that from how smooth it feels or whatever. FSD doesn’t have that reliability, which is why they don’t let you sleep.
