A "fly by wire" system of control and a few positional sensors would make it easy to automate virtually all of this, making it impossible to drive any other way. This has been possible for years, but whether a government dares impose it is a different matter.Also most of us could drive more slowly, reduce unecessary braking through anticipation, not accelerating hard and avoiding short journeys with a cold engine. Don't carry unecessary weight, keep the tyre pressures correct and the engine well maintained.
