Still, some European leaders are hopeful that there's room for progress during the Davos Forum.

Finland's leader went as far as saying he believes it might be possible to defuse the Greenland tension by the end of the week.

My colleague Katie Bindley lives in San Francisco.

She's a tech reporter and therefore has taken a special joy in observing Waymos, the self-driving robot taxis that are all over the city.

I love how you said, I'm lucky enough to be in a neighborhood where Waybos are trained.

Is that really like a stroke of luck?

The car was just listening to TLC?

Recently, though, Katie told me she observed a Waymo doing something that caught her by surprise.

She was in a car with a few other people one night.

They'd rolled up to a four-way stop at about the same time as another car, a Waymo.

Was Waymo's behavior changing?

Were San Francisco's polite, deferential robo-taxis driving a little bit more, well, like us?

So then I started digging into it to see what was happening.
