The average fuel consumption will go higher, as the air drag increases square to the speed, the fuel consumption on those "high-speed" highways will be higher, with higher CO2 emissions, increasing air pollution from common pollutants (NOx,particulate matter), damaging the communities that such highway crosses; I would rather leave the limit as it is.
