Where I currently live, they incentivize people by allowing them to "mothball" their vehicles at will so it stops costing you: if you don't use it, you de-register it for use on public roads, it costs a few euros to do so, and that instantly freezes road tax and insurance payments. If you need to use it again, re-register it on the internet, and it's instantly usable again.

It's nice because you may want to be mostly car-free, but still retain a vehicle - or several - for special occasions. Me, I keep a minivan parked in the garage most of the year, and I use it a few times a year to move furniture or buy oversized items for my workshop of for the garden, and to drive my disabled wife somewhere if she needs to get there fast and can't wait for an accessible cab.

We don't get paid not to drive, but it pays not to drive here. I wonder if the LA incentive offsets the running costs of a keeping a vehicle insured and taxed.
