How about this for a fix? 1. The driver must file a complain with video evidence within 5 minutes of the ride ending. The video evidence should be recorded via Uber app, hence we can mostly trust the timestamp. 2. The passenger entering a vehicle will look around for dirt. If they find it, they make a recording (using Uber app), within first 5 minutes of the ride. Or just refuse the ride. Thus the driver cannot pin dirt created after the ride on the earlier passenger (5 minute limit), and they cannot pin earlier dirt on the passenger (passenger will have reported it). Technically the driver could still smear the car in the space of those 5 minutes after the ride, but that still narrows the window dramatically. And no extra overhead for the mainstream use case (no dirt). As an extra, if the passenger is worried, they can snap a picture/video while exiting the car, as the ride ends (also using the app). Presumably the user is no longer in the vehicle, as evident in the video, and any accusations of them having vomited in the car would not be credible. Did I miss anything? Dunno, or maybe just require dashcam evidence...
