Is AUTHOR wrong in the post ? POST : So I'm trying to get a gauge on what the social norms are in this kind of situation. I called a rideshare carpool and got in the back -- my mom called so I picked up and was making small talk with her about her day. The driver picked up someone else and we continued on our way, and I continued chatting with my mom. 

After a minute or two, the other person said that I was being rude by talking on the phone and that I should stop. She said that she was just trying to get home and didn't want to listen to my conversation. This was surprising to me, since I had always been under the impression that it was normal to have regular-volume conversations in rideshare carpool situations, similar to being in a cafe or public bus. 

Still, rideshare carpools are a fairly recent thing, so I want to see what gut reaction Reddit folks have to these situations. Am I the asshole?
