IMHO anything that cost-effectively shifts the responsibility for the actual driving from "me" to "somebody else" is almost automatically more disruptive than anything that doesn't. (Note the cost-effective requirement, which is important.)

Uber, Lyft are in the "self-driving car" category, not in the "more resource-efficient car" category. Put another way, they conserve a resource (attention) that is far more scarce than fuel, cash, etc.
