It's hard for me to imagine what a "four star Uber ride" looks like. I can think of non-catastrophic issues; maybe the driver has their car details in wrong and is hard to find, or urges you to get out somewhere not that close to the destination because it's a more convenient way to pick up another ride. But a 4-star rating does nothing to solve that, it just adds a bit to the risk of being fired somewhere down the line. Given that, it just feels like a crummy affectation around a "report issue" button. If a driver was actually doing something dangerous, when would I ever want to handle that with one star instead of some actual context like "crossed three lanes with no signal then ran a red light"?
