I rode my motorcycle into a hole that almost swallowed the front tyre entirely in rural Australia. That hole had just been a slight depression that collected water the last time I rode through it, and there was no visual indication that it was now deeper.

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.

Any human can't necessarily tell the difference between an inch of water, which is perfectly safe to drive on (if slow enough that you don't hydroplane), and a flooded street. They can tell the difference between an inch of water and wet pavement, though.
