"NSX" was originally an acronym for "New Sportscar eXperimental". And yes, it was originally NS-X, hyphenated, on the pre-production prototypes.
The NSX is manufactured in Tochigi, Japan.
The air vents on the doors tilt up to direct the air flow towards the passengers. If you pull up a little bit more when they are all the way up, they "click" and lock in place.
Honda simply has better engineers than most other car companies, which is how they went from zero to moderately huge in just two decades. The Accord and Civic are the benchmarks in their respective categories. A few years after they entered Formula One racing, Honda dominated the sport. The NSX is basically the street car built by the Formula One folks.
