I was in a shared Uber ride today, waiting for a couple heading for the SJC airport.
After the driver and I arrived and waited for a couple of minutes, the husband showed up waving at us, while tying his dog to a fence. The wife showed up after another couple of minutes, taking the dog to the car, while the husband went back to retrieve luggage, for a further couple of minutes. When both finally settled in the car, the wife said she could not find her wallet, and took another couple of minutes searching around.
After we were officially ready to take off, the husband said to the driver: do you know how to go to the airport? Turn right here, without even realizing that they might not have the first stop.
Meanwhile, the driver told me (in a language that the couple would not understand) that he could not understand why anyone heading to the airport would want to take a carpool, and (fortunately) ignored the husband and followed the Waze instruction to drop me off.
One best part about Uber/Lyft rides, especially carpools, is the chance to see different kinds of people that do not tend to show up in my usual social circles.
