You are right, that would certainly be a very big contribution and could have been listed as well. Relocating however is a very big step. While I actually don’t own a car myself and seldom needed one, I am hesitant to prescribe that to others as I know the situation outside the bigger cities gets unpleasant very fast when you are not mobile and relocating is a drastic step not available to everyone. In the area of personal mobility, change away from cars could only result from collective action, e.g. drastic improvements to public transport and less from personal choice. (EVs however or hybrids are also a real option for many.)
