Do you feel particularly anxious that you delegated your walking stamina or horsemanship to car manufacturers?
I do feel quite sorry for people living in countries where that is not the case, often due to extensive lobbying from car manufacturers — and as a result are subservient to the severe constraints of car ownership.
Having lived in such an area earlier in my life, my quality of life was absolutely worse off for it, and having to bike on roads only suited to motor vehicles in the southern US summer heat to go grocery shopping or go to school did induce anxiety, yes.
