Because we were talking about what effect a ban on large trailers would have, and that's the only place in the US where there are no large trailers. We could have talked about ~all the capital cities of Europe if you'd preferred. Or the entire island of Britain.
"An intentional misrepresentation, and modification of my quote"
Well, it doesn't get better when I quote the full sentence, but here it is: "Lol do you know how unsafe it would be for 'non-driving' residents if trailers can't unload food and necessary items to NYC?". Large trailers can't unload in Manhattan. 53' trailers can't even be on freeways in much of Europe. It's not unsafe. No one starves.
