And I imagine someone designing product for that weird behavior where I should probably trust it because it's probably a lot better driver than I am, but I don't know, I feel like I can do a better job. Is there anything you've learned about, I don't know, human behavior or how to design software for these sorts of experiences that maybe surprised you or thought was really interesting or that was really important? Shweta Shrivastava: Since you mentioned Tesla, I just want to clarify that it's a different system that we are building, which is for Waymo, we started by solving the problem of fully autonomous driving without a human driver at the wheel from the get-go. It's not a driver assist or aid system which relies on the human driver taking over when there's a complex situation. So I think that expectation is built into that kind of a product and so the human folks who are using that product will also have that mindset that, hey, I should be ready to take over when the situation demands because we've built the system from the get-go to work in a fully autonomous mode without a human driver intervention at the wheel.
