Data from the 2010 Census: 80.7%: Percent of the U.S. population is urban (living in Urbanized area or Urban Cluster).

Sounds like a majority to me.

"Urban" includes second, third, and fourth tier "cities" with low populations and no fleet of Ubers today. There won't be a market for automated ride share for most of the US.
