Is there some benefit to talking to weird Uber drivers I've yet to discover that's comparable with 'going outside at all'?
Yes. "Weird" people are somewhat rare opportunity to build certain social skills.
I enjoy the challenge of finding creative ways to guide the discussion and understand their headspace for a little while. I am not even trying to control the level of weirdness, but just keep them talking and comfortable.
Unfortunately, most of the time they're not even weird people and it was just a weird first impression. They vent for like 3 minutes and then it gets boring again.
Interaction with the common person is great. I wouldn't have know one could trim their toenails while driving otherwise.
