I tried to do it, actually.
1. I have no need for extra money.
2. I drive an oddball 2 door electric so Uber and Lyft said no.
3. I would love to help someone get to a destination cheap or even free if I'm heading that way.
I scheduled rides (even to the store, etc) way in advance and never had a single bite -- even though I live in a very busy area and drive to very busy areas.
I would LOVE for Google to connect me to riders, even if it was free, just so I could help folks out.
I have zero fear of someone kidnapping me. I'm armed anyway.
