It's my pet-conspiracy-theory that the government, ruling that 80kph (~50MPH) shall be the new maximum authorized speed on national roads compared to 90kph (~56MPH), saw that law-abiding citizens would respect the new limit, that fuel economy would be improved as a result, leading to less gas sale, and added more taxes to make up for the loss.
