Rating every single ride on a transportation service is nuts. It's a burden on the client to have the feeling that he needs to rate and it's a stress on the driver.

If there's something wrong with the ride, like tardiness, inefficiency, bad vehicle or filth you should be able to report that explicitly. That way the driver can learn and improve. When the complaints exceed a threshold, there's a consequence.

The popularity contest with the stars is meaningless and stressful.
