Yeah, that's the point. The less drivers, the better. It would be unpopular (and perhaps illegal?) to forbid cars, but they can sure make it incredibly unpleasant to drive, so that people simply give up. I support this.
I love bikes but also have a car which is an absolute necessity. Simple example: picking up a friend or partner from a medical appointment where they're in a state that would be unsafe for them to ride public transit or even a rideshare. They could pay through the nose for a specialized medical rideshare, or I could just pick them up in my car.
