That's the same calculation people do when thinking about vegetarianism or veganism. What's the benefit of replacing all of your turkey with tofurkey? Well, no, most vegetarians don't simply replace all of their meat with fake meat any more than people with cars replace all of their rides with Lyft.
Consider:
* Many households have two cars. I might "ditch owning a personal car" if I know I can occasionally borrow one, or if my husband/wife/etc can drop me off at work a couple days a week, and maybe I can use Lyft sometimes when the household car isn't available.
* Many people don't drive to work even if they have a car. Maybe you own a car for occasional errands.
* The cost of parking in some cities is prohibitive. Do you not pay for parking? I recognize that I live in an expensive city, but if I commuted by car I would likely be paying over $5,000 per year for parking alone.
* Some people have much higher insurance costs, and not necessarily due to fault of their own (e.g. single 20-year-old male drivers).
* Not everyone is willing to buy cheap cars off Craigslist, and most people don't do their own maintenance.
