Just curious as to a question my wife asked me... What is the standard gas mileage cars get around the world?? I would imagine that US cars are somewhere around 18-20/20-26 MPG on average. I was out shopping yesterday looking at cars... The Ho0nda Civic was one of the best at 30/38 MPG. (city/highway)... Most seemed to be around 18/24 or 20/26. Was NOT looking at trucks, Minivans, Vans, SUV... just the economy class sedans.
