It's nice to know that there are forward thinkers in government. Arizona has just revamped its alternative fuel vehicles statute. Now, instead of bi-fuel vehicles (cars that run on gas OR an alternative fuel) being able to use the HOV/carpool lanes, only cars with a 45% or better fuel efficiency qualify. Right now that means the Honda Insight or Civic Hybrid or the Toyota Prius.
Finally we'll get the huge SUVs with single drivers out of the HOV lanes. Many people purchased these SUVs because of an ill conceived Arizona law that subsidized the purchase if you altered it to run on gas or an alternative fuel. So a bunch of people collected big subsidies to buy their new SUVs and now run in the HOV lanes even though they're burning gas. Oops! Well, that's finally been fixed and now the alternative fuels statute is a high efficiency statute.
It may be a small step forward, but it's a step all the same.
