But if you can't show that "100% solar & vegetarian" is a viable & desirable choice, you're not going to convince others to. Imposition under threat of police action will only invoke shifting bad choices, strain economy, and inspire malice.

As I recall from the time, the rise of the SUV came from imposition of emissions limits on cars, which didn't cover trucks so the spacious & fumes-spewing "enclosed car-styled truck" was inspired. Did that help emissions in the long run? Here in the southern USA, 2/3rds of vehicles aren't emissions-efficient sedans.
