To go "car free" is one thing. To avoid the use of a
vehicle altogther is quite another.
Not owning and using a vehicle is fine for those who wish to.
However, is makes sense to maintain your legal abilty to drive
for those rare times when the correct vehicle for the job is
a car, pickup etc. These can be rented as needed while still
being "car free" .
One can not drive because one chooses not to. On the other
hand one must be practical in what one does. To do
othewise is to labled as 'foolish" or eccentric and rightly
so.
