I respect the hell out of that!

The car, when used for all transport, is wildly inefficient. Multimodal transport where whatever mode is most efficient is used, isn't applied enough.

You like driving. If the goal is to enjoy the pleasure of driving, then no other option serves that purpose. Hence, driving is what YOU should be doing.

But cars are used to achieve so many other goals that do have more efficient options, simply because it is the existing standard.

There are people who VEHEMENTLY HATE commuting by car. They shouldn't be driving, but doing so might still be the least offensive option. Providing these people a way not to drive, also fits the description of "discouraging" car ownership.

Cultural knee-jerk reactions like yours, as well as the barrier of existing infrastructure, make improvement difficult. OP is specifically asking how to change things in a way that would make people want the change, rather than have it be forced on them.

They didn't ask how to stop people from owning cars. Discourage means discourage. If you'll never sell your car no matter what, that means you're one of the people who can't be discouraged, but that doesn't mean people who can, and even should be, don't exist.

You admit to using transit systems, when applicable, which means you're already accepting the solution. Would it really be so bad if you could use transit to get more places, and more people could use it for all their needs, even if you aren't one of them?
