In 2017 I returned to America from living overseas. My mom passed away early in the year and I wanted nothing to do with shopping for a car, much less driving a car. So I just took Lyft to my new job until I had my feet under me and felt up to driving again. In the end I never felt up to driving full time. I now share my wife's car (we did get her a car eventually), but we only purchased the 1 car. We either ride in…
> Either way, "ride sharing" has definitely taken one more full time car off the road one more full time car out of the parking lot.
However, when multiple people use a lyft car throughout the day, it is more efficient than having each person own their own car. Maintenance, insurance, and the construction of the car itself are all shared.
Perhaps it's half a full time car off the road.
