According to the search results, a bad Uber rating is generally considered to be anything below 4.5 stars. However, opinions on what constitutes a bad rating can vary among drivers. Some drivers may not accept rides from passengers with ratings below 4.6, while others may be willing to accept ratings as low as 1.5. Its worth noting that a low rating can bring down a passengers overall average score and may result in fewer drivers willing to pick them up. Passengers can check their rating in the Uber app, and the rating is typically an average of their most recent rides.
