You have to calibrate it, et cetera.

It creates bloat and entropy.

You have to be really sure that you need this sensor.

In this case, I basically don't think you need it.

And I think, honestly, I will make a stronger statement.

I think the others, some of the other companies that are using it are probably going to drop it.

Yeah, another way to look at it is like vision is necessary in the sense that the world is designed for human visual consumption.

So you need vision.

It's necessary.

And then also it is sufficient because it has all the information that you need for driving.

And humans, obviously, have a vision to drive.

So it's both necessary and sufficient.

So you want to focus resources.

And you have to be really sure if you're going to bring in other sensors.

You could add sensors to infinity.

At some point, you need to draw the line.

And I think in this case, you have to really consider the full cost of any one sensor that you're adopting.

And do you really need it?

And I think the answer in this case is no.

I think, as you mentioned, they pre-map all the environments, and they need to refresh the map.
