Not in the past few years - SF only. But I do appreciate that Lyft is active elsewhere in the US, just that Uber appear to be active in a LOT of markets where Lyft is not (i.e. there are places in the world that are not major US cities).

Certainly Uber is more places but in the past 2 weeks I've spent time in "cities" of sizes around 50-60k people and almost all have had both services. Often Lyft will have less cars on the road but I did not struggle to find a Lyft.
