For larger areas I am not seeing Charleston WV on their list of cities. Though this would be easier if they showed a single map across the US.
Think smaller, Charles town WV official population 5,957 has taxi service. Edit: that was under the Baltimore map even though DC was closer. https://www.uber.com/global/en/cities/baltimore/
Fair enough. There are indeed some very small towns where Uber hasn't changed anything. Despite that, I stand by my assertion that the company changed the world in a real way.
I also think they'll get the the Charles Town WVs of the world at some point.
If that's getting done for SC (a relatively un-dense state) I think they're covering pretty much everywhere in the US.
TBH I think the page you linked to is more about SEO than about Uber's actual coverage.
Can you tell me a specific place that has good coverage from cabs where Uber doesn't operate?
