Yea it's kinda tough to really be "eco friendly".
The alternative fuel sources have their own problems, Not enough farm land to grow bio fuel crops, propane is a by-product of
oil refinement, electric justs shifts the emissions to the power plants. (unless you have hydro electric like 2% of the country)
Gasious fuels like hydrogen and propane are dangerous and more easily ignited so accidents and re-fueling will kill more people than air bags save.
As far a legislature goes, well, I've seen mandetory seat belt laws added and the mandatory motorcycle helmet law repealed here.
Still waiting on the killer bees, the utter collapse of mankind from Y2K and the ozone hole, half the country infected with AIDS by 2000, Altzhimer's from my aluminum pans... However any law can be bent with the proper funding.
