Describing Montreal as "sheer chaos" only makes sense in the north American context. Karachi and other such cities are actually chaos.

I was thinking this too - my guess is the cars simply wouldn't offer rides on days with really poor conditions.

Toronto's winter driving is normally very reasonable compared to Montreal. My guess is the Waymos operate some ~355 days a year, taking days off after big storms.

They have a limited presence in New Orleans, mostly rolling around the French Quarter and Uptown. The roads look bombed out in parts of Uptown, maybe not the absolute worst anywhere but it's close.

There is no chaos there, just traffic jams.

They've been mapping, or whatever they do, Pittsburgh for almost a year now, and it was pretty funny watching the cars navigate around massive snow piles last winter. Curious to see how the rollout goes here. <Insert popcorn emoji.>

Denver just launched ahead of a supposed "Super El Nino" winter. We'll see what happens.

on the other hand, montreal doesn't allow right on red, and instead has an extremely strongly planned traffic grid including priority right turns. Not much ambiguity in the prescribed traffic patterns.

>> Montreal would be the ultimate test, both climatically and just for navigating sheer chaos.

Montreal is a vacation compared to the great plains/prairies: -40 with half the road coved by blown snow. Lets see how the navigation system reacts to a total absence of painted lines and visible curbs. Or go to the rocky mountains. I doubt Montreal streets contain any mountain passes worthy of naming.

The ultimate test would be Cairo or Mumbai or Lagos :-)
