Are you aware of any anecdotes of people saying their rating fell when they didn't flirt back or got on crutches or something? (Your point is still valid even if you don't, I'm just interested)

The big one no one is talking about are non-tippers.

It's becoming downright common for Uber drivers to outright admit they give 1 star ratings for non-cash-tippers.

But yes, I've anecdotally heard of ratings drop for women who typically are type-A chatty, but changed to quiet and withdrawn for a few weeks during major life events. Perhaps that came across as more surely, but just something as silly as someone perceiving a bad attitude from a rider can results in a lower rating score.

I've also talked to drivers who give poor ratings if they have to go well out of their way, and it ends up being a short ride. Sure, this really sucks for the driver - but is it the rider's fault at all? Other unpopular destinations get similar treatment (or so I've heard).

My Uber rating fell noticeably while I was on crutches for around 6 months, it has since risen. This is in Boston.

My rating drops when I want to go somewhere far away or in busy traffic, I don't feel like talking to drivers or just use uber pool / lyft line.
