Addressing the hypothetical person you’re describing: car infrastructure may solve some needs, but it is in direct conflict with other needs. Give every adult a guaranteed parking space just at home and at work, and the physical space required for that alone is an unbelievable double-digit percentage of the city area. Cities are so valuable because they pack a lot of amenities and markets (including your family’s schools and workplaces) in a compact area. Place everything significantly further apart, add more concrete and noise, and you’ve lost on all fronts: safety, charm and efficiency.
