[DMCForum] Re: Passing Gas

Ok, I get your point. Obviously I haven't read up enough on how
hybrid cars work because somehow they have overcome all this.

Yes, we have LP cars, but they are usually purchased by large
companies with large fleets of vehicles and state and municipal
governments. There are not many LP fueling stations around for
private citizens.

Um...while you guys are bashing Bill and his carb'd PRV...you should
know that the damn thing came with an LP carb on it. It's set to burn
LP right now.
