While I'm certainly no ridesharing apologist, Uber/Lyft have raised the bar significantly in terms of forcing drivers to do basic things that cabs simply failed to do in most places:

1) Actually freakin' show up.

2) Not take the lifetime of the universe showing up

3) Accept credit cards

4) Clean their car occasionally

I can go on ...

If Uber/Lyft completely flame out, I would not like to see these things go back to the way they used to be.
