Ride sharing drivers can pick up in the area they drop-off, though

  Triangle inequality still holds, sorry to say It only makes sense if they are transporting two or more people that would otherwise have used two or more vehicles. But I think that kind of rideshare system is the absolute minority of Uber and Lyft rides.

    Yes, the reduction is over vehicles (fewer unique vehicles), not vehicle miles.

    Perhaps, but with ride sharing you're less likely to make more stops, preferring to get to your destination in one continuous trip. And if you ditch your car in favour of ride sharing, then you're likely to make less trips overall. You'll think twice before driving somewhere you could otherwise walk, more so than if you owned a car. And you're less likely to make impulse trips that can be avoided (to get a chocolate bar you're craving or something else pointless). At least, I'd imagine that's the case - as there is the additional time of hailing a ride with one of these services and a more measurable cost to it.
