They're already learning how to handle this in SF. (I don't live there anymore, so I can't give specific examples.)

Waymo markets itself as an automated driver - same reason they're using off-the-shelf cars and not the cartoony concepts they originally showed. Like real drivers, they take the law as guidelines more than rules.

De jure (what the law says) and de facto (what a cop enforces) rules have had a gap between them for decades. It's built into the system - police judgement is supposed to be an exhaust valve. As a civil libertarian, it's maddening in both directions:

- It's not just that we have a system where it's expected that everyone goes 15mph faster than posted, because it gives police an avenue to harass anyone simply for behaving as expected, and

- It's also dystopian to see police judgement be replaced with automated enforcement. There are whole classes of things that shouldn't be penalized that are technically illegal, and we've historically relied on police to be reasonable about what they enforce. Is it anybody's business if you're speeding where there's nobody to harm? Maybe encoding "judgment" into rules will be more fair in the long run, but it is also coaching new generations to expect there to be more rules and more enforcement. Feels like a ratchet where things that weren't meant to be penalized are becoming so over time, as more rules beget more automated, pedantic enforcement.

A slight digression, and clearly one I have a lot of thoughts on.

It's really interesting to see how automation is handling the other side of this - how you build machines to follow laws that aren't enforced at face value. They can't program them to behave like actual robots - going 24 mph, stopping exactly 12" before the stop line, waiting until there are no pedestrians anywhere before moving. Humans won't know how to interact with them (cause they're missing all the nonverbal communication that happens on the road), and those who understand their limits will take advantage of them in the ways you've stated.

So Waymo is programming a driver, trying to encode the behaviors and nonverbal communication that a human learns by participating in the road system. That means they have to program robots that go a bit over the speed limit, creep into the intersection before the turn is all the way clear, defend against being cut off, etc. In other words, they're building machines that follow the de facto rules of the road, which mean they may need to be ready to break the de jure laws like everyone else does.
