That isn't quite what I read out of the OP. I may have misread it ...

OP was columnist George Will. As I recall he wrote that for every
10% improvement in fuel economy Americans drive 2% farther.
Therefore that imprevement MAY (or might) result in more fuel
use.

His use of the conditional indicates that he didn't even know how to
do arithmetic. That a supposedly intelligent person would publish
such a statement is a sad commentary on the level of education
in our society.

Your other comments, about how the _price_ of fuel is plainly the
more important factor regarding fuel usage, are well-taken.
