But don't let good be the enemy of better either. I think it's important to realize that "People will always use cars" and "We can and should reduce car usage" are not contradictory. We need to both offer and incentivize alternatives, find ways to reduce car dependency, etc and make sure that remaining car usage is as clean as possible. (This applies to both the car usage that we can get rid of in the mid- to long-term but haven't yet and the "residual" car usage that we can't seem to get rid of.)
