Uber and Lyft are popular with younger people, city dwellers, and college graduates, and a lot of mass media content is made by young college graduates living in cities. But as a whole, the American population is older and more suburban than it's ever been — so it should perhaps come as no surprise that the vast majority of people have never used a ride-hailing app.
Indeed, according to this great reality check from Pew, about twice as many people have never even heard of these services as have actually used one.
But for now, at least, what Uber and Lyft have done is revolutionize the urban taxi industry, which is a big deal in a handful of cities but pretty minor in terms of its impact on the lives of the vast majority of Americans.
