Waymo's remote support can't drive the car. I'm surprised by how many people seem to have assumed that would be a good idea. What happens when, inevitably, there's a communication fault while driving in this way ?
It's pretty clear that with Waymo the first response is to fail safe: when in doubt, pull over and ask for help. I was expecting that the help could include a semi-assisted remote override mode. The remote support would not be turning the wheel and pressing the gas, but giving it higher-level overrides, like "do a u-turn here". So in that case if it loses touch it's reasonable to resume traveling if it now can or once again pull over and ask for help.
So either you're no worse off, or the link is fine and you don't need to send someone out at all. Sounds pretty good to me!
Like I said originally, if it was safe for the car to be driving itself it already would be.
