Ridesharing solves one particular use case - some trip where either parking is too expensive, too much of a hassle, or both. It's great for quick trips into town or to the bar or to the airport. For pretty much every other use case, it is either too expensive, too inconvenient, or both. No one is about to sell their car for ridesharing if they need to ferry around their kid for extracurriculars, or go to the Costco and pick up lots of bulky items, or want to go skiing on the weekend; you need more drastic interventions for that, like reducing the availability or convenience of parking.
