Just wait...although it sounds GREAT, Californians will soon find themselves in the same situation as we have here in N. VA. Everyone will rush out to buy that Priuis or Honda Civic Hybrid. Then no one will want to carpool. Then.....the HOV lanes will be clogged with single driver hybrids. Kinda' defeats the purpose of HOV lanes, don't it?
BTW, a study last year found that at certain times of the day...it actually takes MORE time because of congestion(primarily b/c of the hybrid exception) in the HOV lanes than the regular traffic lanes on I-395 into DC!
Another consequence will be a shortage of hybrids and thus higher prices as everyone rushes out to buy a Prius so they can use the HOV lanes.
That's why VA's HOV exemption will expire next summer.
