Not really. In transit poor cities people own cars and drive their own cars. In transit rich cities you can feasibly live without a car and use rideshare to fill in the occasional gap. Transit and rideshare are complementary. Only rich people and businesses use rideshare as chauffeur rather than necessary transportation.
Not necessarily. When on vacation I used rideshare everywhere I went in Texas as I didnt rent a car. When I lived in Texas I had my own car because ride share isnt an option I could use regularly. In NYC I never needed ride share at all. I used it once in a blue moon. NYC grew in population but number of transit riders has remained steady or declined since 2015. Even the NYT did an article on 8/2018 linking Uber to the decline in transit usage.
