With all the computing power and vision AI available in such a vehicle, it seems like it would be possible to perform an automated interior scan of the cabin after each ride. Detecting cleanliness issues(and forgotten baggage).

Might be difficult to detect if someone peed though unless you can make the interior highlight it somehow. Maybe a moisture detector could be added but could be difficult to calibrate that for rainy days.
