I don't see that as a problem at all. What it means is that your Uber driver is going to be super-nice to you and you will very likely have a very pleasant experience.
I've taken taxi rides over the years and as often as not I run into a crabby driver in a bad mood. Never happens with Uber. No wonder the taxi drivers are all up in arms. Companies like Uber and Lyft are going to run them right out of business - and deservedly so.
You could be the nicest and most polite person in the world and you can give the best possible service in all of history as well. You could pick them up and give them the most gentle and efficient ride that physics will allow. The sky could be a bright and deep blue hue and the bluebirds could sing. When you pick them up, you put their suitcase in the vehicle and you drop them off. You give them a nice cold bottle of water as a complimentary gift in appreciation for their being your customer. During the ride, you talk about whatever your ride wants to and when you drop them off, you carry their bad to their front door. Then, you drive off secure in the knowledge that you secured a five star rating from this.
You find out they rated you a one because they just didn’t like you.
