My wife & I live in San Francisco. SF Muni fares are a flat $2.50.
So for the two of us, a Muni trip is
- total cost: $5
- usually takes 30-60 min to get wherever we want to go in the city.
- we need to to figure out the optimal route, schedule, and entry & exit stops.
- we need to make sure we will arrive at the stop on-time.
- we need to walk 5-10 min to closest stop on either end
This process is familiar to anyone who's taken public transportation. In general, I think it's a great system. Muni network coverage is pretty good in SF.
However... a low-cost Uber or Lyfts pool ride for two is
- total cost: $5-12 (same serice area as Muni)
- duration: 15-45 min
- we don't have to plan the route or schedule
- we don't have to worry about going to a remote pick-up stop on-time
- we get dropped off directly at our destination
So, in the best case scenario, a lyft line ride is the same cost as Muni but so so much better in terms of value to us. Even when it is 2x as expensive, for us, the extra $5 is totally worth it. I know that's not true for everyone, but I personally am amazed that the cost of using the cheapest ride share option is often only 1x-2x the cost of using the billion-dollar municipal public transportation system.
Of course, here in SF ride share vehicles are definitely not allowed to use the special public-transportation-only lanes of some of the major roads, which remain reserved for the exclusive use of Muni buses and taxis to improve their transit times.
