Riding in an Uber Pool has always been perfectly pleasant for me. Quiet and awkward in some cases, but not unpleasant. Some basic restrictions about not cramming people into the vehicle like it's a clown car should alleviate most concerns about unpleasantness, I'd think.
Sorry if that was unclear. 2 pickups, 2 drop offs.
I wanted to make clear that we didn't just pick the people up. But they were both dropped off first too. Worse yet, the other destinations meant that for my 20 mile drive, we drove through residential the whole time.
