Because that would be wrong. Wind resistance is the biggest loss at hiway speeds, more so than weight. Now city driving weight is the biggest factor, and not so much wind resistance. There is 2x the air mass per volume at -40 C than at +40 C.

And cold air is more dense and in turn requires your injectors to give more fuel to prevent too lean of a mixture.
