Fuel economy higher at 55 is a myth. It’s depends on the vehicle entirely and the vast majority see increases until 65+. Speed limits are set to allow safe travel based on the flow of traffic, not control mpg. You can EASILY drive 55 average speed and blow through more fuel than someone who drives consciously at 65/70. This, among the other things you’ve said, is a really dumb take.
