Nope. We use inches and feet. Still, since the Elio will be sold only in the US, it makes sense to use the same system that is used in the US. I'm not saying it makes sense or that everyone else should change to the system. I'm just saying that if you are talking about mileage of a vehicle that will only be sold in the US and the people you are talking to (reservationists who are IN the US make up probably 99% of the audience), you should use the system they use. Maybe we should mention that the Elio weighs 89 Stones because that makes just as much sense.
