This is the naive "if you can't stop you're following too close" circular definition based take. Makes for good rightthink points on reddit and communities of similar quality membership but you're not actually gonna build anything useful thinking like that.

In order to drive reasonably humans need to drive through water that is 6-12in deep on occasion. That's just how it is. Near me it's whenever the storm drain at the bottom of the hill clogs.

Why do you ignore the context (humans cannot distinguish?). If what you say is true, Waymos are useless in your areas. Thank you for confirming this!

As opposed to the "don't ever allow for rare/unexpected events where following too close leads to a collision" stupidity based take.
