I think you live in cities and look at everything from those lenses. Car rental is still thriving for business travels. Hertz actually served business customers more than Budget etc. When you go to places like Bay Area, Hawaii, Pudget Sound etc car rental is many time unavoidable. I don’t think Hertz went bankrupt because of ride share as OP suggests. There was another article which states how activist investors took over and loaded it up with debt transferring their assets.
