Apparently they make cars that run on natural gas. Where do you even _get_ that fuel?

@Felthry It's not too uncommon here to have gas stations with refuel points for those.
@Nomaxice I would guess natural gas refers specifically to LPG, since having it actually stored as a gas would be inconvenient to say the least
There must be some in the US, as there are cars available here that use it, but I've never seen a gas station that offers it
I think I have heard of buses using LPG before though now that I think of it, so maybe fueling stations that focus on trucks and buses would be more likely to have it.
@Felthry That's it yep! Or "GPL" in french.
My stepfather had a car that was "hybrid", could run on regular gas or LPG, and I know he refueled it at least at a supermarket gas station that offered it, pretty sure I could try and find more with an online search.
@Nomaxice That's fine! I'm asking out of curiosity, not any actual need to know.
@Felthry I think you can still find some LPG powered vehicle but they're pretty rare, I'm afraid I can't really provide more knowledge on that
