I would think the idea is that Uber/Lyft, in the long run, disinsentivizes individual car ownership (why own a car when I can take an uber?) except for those doing the driving for Uber/Lyft. So the overall dynamic might shifts from lots of people owning cars (but relatively low utilization rate) to a few people owning cars (with very high utilization rates).
