The judgement exists because construction is happening in economies around the world but only Americans drive this many large vehicles. Unless you think Americans are building _more_ than other economies (which it definitely isn't), you'll quickly come to the conclusion that because parking and large lane widths are mandated by local code and vehicle weight isn't really taxed in any way, that Americans have an incentive to buy as big a car as they can that fits within their government mandated built environment.
