Not OP, but I can say from personal observation/experience that while not 'small', Uber has increased taxi use in the general sense in Texas cities that are so car-centric and-or sprawl-like that traditional taxi services were never really popular (Houston, Austin, Dallas, etc) - having more drivers available in an ad-hoc manner has made the dispatch time much more reasonable (minutes vs a hit-or-miss scheduling ordeal of ~1h) and so using taxis (e.g. Uber) as a viable means of transportation, especially for things like social events, is much more common than it was before. I suspect the same is likely in similar places where 'everyone has a car' and the geography is very spread out.
