The big advantage of having your own driveway is it's always available when you want to park. No need to look for parking and no risk of someone else taking the space you shoveled. We already give people with driveways de-facto exclusive rights to an approximately car-sized bit of street; what if you could keep the parking rights to that bit of street, and the right to put things back as they were, even if your tore up your driveway and put something else there?
(If you can get a whole side of a street to switch from on-street parking to driveways you make more room in the street. But if there are any houses that don't have room for driveways that's probably not doable.)
