> LPG vehicles incur costs similar to other alt-fuel vehicles without enjoying

Not universally true. In Italy, where regular gas prices are stellar, LPG is a relatively common thing. Not common enough, but the infrastructure is "there" (although not as capillary as regular gas) and it's advertised as a consumer option.

You're right, I was American-centric. It's a land littered with gas stations and finding other fuels can be extremely challenging.
