As long as those cars are at home in the garage instead of on the road that's fine. The point is having fewer cars on the road, not fewer cars in general. Riding around on a bicycle and having a car for exceptional circumstances and a once a year road trip is healthier and safer than driving that car around every single day.

How do you know? I know many parents who move their kids around in bikes (many of those live in cities with less than 200k people) who specifically opted not own cars.

I particular I know that many schools in Germany have car free zones around them due to the problems that car drop offs cause (there is nothing worse as a rushed parent in an SUV dropping their kids off at school. The number of near misses I have seen and experienced makes we want to globally forbid cars within 2 km of a school).

That is definitely not true in many parts of Japan.

In Amsterdam I guarantee you they don’t.
