You don't want to block a driveway, you don't want to double park, although in some cases where if it's a quick one, maybe it's okay.

So there's a lot of nuance that goes into doing that well so that it's a smoothless, frictionless experience for the rider as well as other folks.

Freeways, for most drivers,

of the time, not much happens.

They're very well structured because we designed them that way.

But there is still that long tail of really complicated stuff that happens where the consequences

of a bad event are much more severe, right?

Speed is much higher.

Everything is quadratic in speed.

But we see a lot of stuff.

Imagine grills falling off of freeways.

Imagine people getting into accidents and kind of spinning out of control.

I would say the, yeah, it's not like, you know, we're done with engineering.

I would say that

we've clearly moved past the stage of scientific research and deep core technology development to this new phase of accelerated global scaling and deployment.

We still have work to do, but I don't see today any limitations or any gaps in the core technology.

The driving is good enough now.

Well, the core technology, I think, is good enough that I can't think of any aspect of driving that is not supported by the fundamental technology.

Now, that said, there is a lot of work to do in specialization and in validation before we can deploy responsibly.

We're not driving everywhere in the world.
