This is not the case for likely 90% of the country. Note that I'm currently in Chicago where we have much better public transit (in addition to rideshare) options than you do in Los Angeles, but most of America doesn't have the population density to support it.
I'm in Chicago as well. Yesterday I had to go downtown during rush hour and Lyft wanted $15. I'm not sure if this is normal (although I believe we have a hefty tax on rideshare to downtown, at least during rush hour), but at that point it's significantly cheaper to pay the $10/day or whatever that the parking garages charge (of course this isn't factoring in the cost of ownership nor is it considering other transit options).
