Houston did this a few years back $1.5mil to change all the signs in and around Houston... they changed it back less than 3 months later because nobody gave a shit. They can change the speed limit, but I think the gas saved from people who follow the new speed limit is going to be offset by the people going WOT to pass that slow #*&@&*#!
TX raised the speed limit on I-10 West of San Antonio to 80, there are no cops out there just desert. There is only a speedlimit because they are required to have one for Fed. funding.
