I guess it started with &quot;roads are unwalkable&quot; and then slowly morphed into &quot;Americans wouldn&#x27;t walk anyway&quot;, and you can see it in the comments here.<p>Most people can&#x27;t even come up with a sane rationalization of their environmentally hazardous laziness. Instead it&#x27;s &quot;America is such a big place&quot;, which is like saying you can&#x27;t bike because Russia is the biggest country on earth while you live in Moscow.
