This is slightly detrimental to the driver. Anything less than 5-stars is basically negative.

I’ve had a perfect 5.0 rating over 500 rides but would occasionally get lower ratings or 1-star for reasons I didn’t know. Bad smell outside comes through the vent? May a strong short stop in ridiculous traffic?

The ratings were meaningless to me, there’s no actionable result you can make. It just tormented me with some anonymous, ambiguous criticism of a already super stressful job that paid $20/hour.
