How can you see what rating you get before leaving a reciprocal rating? I don't see any sort of way to see individual ratings on a per-trip basis.

Sneaky but you can casually linger in the car for an extra second; most drivers rate you right as you're getting out, with a phone that's usually mounted within eyeshot of passenger seats.

The ones who will give you 5 stars usually do it right away in front of you; if they seem weirdly secretive about it, you're probably not getting 5 stars.

With 3 digits of precision, not a massive amount of rides, each rating will make it go up or down.

Won’t work too well if you frequently take a lot of rides.

If I were creating the rules to analyze this data, I'd have to question the entries that were the difference between the driver and passenger is high.
