If there are fewer cars on the road, there is a lot less traffic, and driving because much easier for those who are car-dependent. Example: the Netherlands.
Yes, but they're used less frequently. Most middle class people have a car, but they're often only used for irregular trips. Commuting and errands use alternative means at much higher rates than elsewhere.
Point is, they still need cars if they have them. And Netherlands are very far from Paris, infrastructure-wise. In Paris, for instance, leaving your cargo or e-bike outside for the night means finding nothing when you wake up (I got two bikes stolen already, and they were the cheapest available).
The topic of the original post is air pollution. Unused cars don't cause air pollution. The topic of this thread is inconveniencing the disabled. Unused cars don't cause traffic that inconveniences the disabled.
Paris tackled the problem by making it very hard to own a car. It's the same for Amsterdam, too. We all hate pollution, it's just that the solutions available in the Dutch countryside are a bit different than in Paris.
