What's the point here? Then you'll need another car?
Remember, we're comparing to iPads. Apple intentionally hobbles them to induce demand for multiple iPads. This isn't a question of being allowed to own multiple iPads/cars. It's a question of being artificially prevented from owning a single one.
The point isn't that you have to commit to being a single-car household for life. It's that at some points in time, you can be.
I was already on my thirties when I got my first car.
