What in this list would you do differently? I'm probably a weirdo with insufficient empathy, but I have a hard time imagining how a civilized person would behave otherwise.

I get into the car, surf the web and never talk to the driver. Occasionally if driver starts a discussion I give short answers so it stops quickly. My rating is fine and I enjoy no human interaction

You never say anything at all? I mean, like, you open the door, sit down, when he stops where you're supposed to be you just get out and don't acknowledge the driver at all?

Sure I don't chat with taxi drivers unless I feel like it but you at least say 'hi' and 'thanks' when you get in and out, or not?

Of course i say hi & thanks, these are "handshake" words I use automatically interacting with anyone. But no smalltalk, and outside the US, drivers are often silent too

Oh OK, yeah that's how I interpreted the GP as well, so then I still wonder how the steps described aren't the default or even just blindingly obvious to the point that doing anything else is weird. I mean I can see when someone is drunk and is annoying, but apart from that.

Obviously you don't have to follow that script verbatim. It's just a manner of behaving like a civilized person.

Edit: that said, the quotes from Steeeve below do start to sound pretty Black Mirror
