I've never used a rideshare but I would love to have a driver that didn't want to talk. "Where are you going and We're here" is all the conversation I would want. I would expect that there are others who would feel the same. Is there any way that you can advertise yourself as non-talker?

You could drive people and just be honest with the passengers. "Hey, I'm X. I'm not a big fan of small talk. I plan to leave you in peace to check your email, or do whatever, but I will try to answer questions if you have them." If they ask something too personal, you can always say, "Oh, I don't discuss that with people I don't know. " Maybe I am erroneously over-simplifying?

I call myself an introvert, but I'd much rather talk to a person than a hamburger. And I suspect you still get to talk to a person when delivering that cold burger and soggy fries... and maybe less pleasant. It's crowds that suck my energy. I love to make quick conversation with cashiers, haircutters, contractors and whomever I'm thrown-in with on a 1-to-1 basis for a short time. Most people have an interesting story if you can pry it out of them in the allotted time. Ya just have to never argue or disagree when driving someone! And just shut up if you sense that's their preference.
