Waymo granted permit to begin testing in New York City

I would argue those two areas are very different though. The Bay Area is not as dense or as many aggressive drivers as NYC.

This always astounds me about cities who have a reputation for people breaking certain traffic laws. In St. Louis, people run red lights for 5+ seconds after it turns red, and no one seems to care to solve it, but if they'd just station police at some worst-offender lights for a couple months to write tickets, people would catch on pretty quickly that it's not worth the risk. I have similar thoughts on people using their phones at red lights and people running stop signs.

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.

I think the problem in NYC will be getting medallions, assuming that's what self driving cars will need.

There are already so many (too many?) taxis and car sharing drivers, after TLC's massive increases of the last few years. You can play a game, based on something I read about last year: stand at a corner and count all cars/trucks/for-hire. The first two combined are barely outnumbered by the last group. And the few times I checked, half of taxis and car sharing vehicles were empty. (Of course that's different at peak times or when it rains.)

Will Waymo be allowed to add as many vehicles as they want, like a new class of cars, or will they need to buy out medallions from drivers? The former might undo all the progress in traffic relief that was brought by congestion pricing.

NYC (at least the parts I've spent a bit of time in) is pretty grid like with fairly simple roads. The drivers are the hard part :)

I am excited to see them tackle Boston at some point because of how strange some of those roads are. The first time I had ever been I came to an intersection that was all one ways and there were like 7 entry/exit points. My GPS said turn left, but there were three paths I'd consider left. Thank god I was walking.

And I don't really pose much doubt because it seems like Waymo's rollout plan has been solid, but I'm just interested to see how well they tackle different cities.
