They were intended originally for the Japanese Domestic, Austrial Asia, and Europe Markets. The R30 and later versions were built to compete in the now JGTC, European touring car, and Austrailasia'n racing car series. Nissan, again this is a personal view, never though or intended on selling them world wide. If they had they would have built a left hand driver version.
This brings me to part of your question. They are illegal due to they were never sold or intended on being sold in the Western markets. Therefore without that they are classed as they are they are in Canada and the United States.

As far as being hated that is due primarily to all the hype, of which most is overboard. While the GTR is and will remain, in my opinion, the wholy grail of Japanese performance cars, it is however not the be all end all car as some claim or make it out to be. As much as I would like it to be it is just fact it isn't. Too heavy and big for ralley, and small tight circuts, but on the bigger tracks where it can stretch its legs and performance ability it is without a doubt one of if not the best overall package out of the box.
