I Dont Understand

Why both drivers and customers can rate each other but not fairly. It seems that now days, drivers are expecting TIPS. Why is this? When theyre getting paid to drive us to our destination. If we didnt want to save money. Then wed catch a cab. Theres no reason for drivers to give us customers low ratings if we havent done anything wrong. I am a very considerate person, I greet the driver, depending on the vibe they give off. May spark a conversation or just be silent. I ask before rolling their window down if Im hot and look out at the scenery as we arrive to my
Destination. I had 5 stars for the longest time. Until, recently a driver rated me low (I wish there was at least a comment section to prove that there was nothing inconsiderate that happened or at least he could comment on what I did wrong) now Im down to 4.4 stars.
