Oh I agree, but unlike when NCAP first came out, its not something OEM's push to the front, because much like crash helmets, everything pretty much is top rated - so you don't really look...
I've got proactive passenger protection on my GTI.... I didn't spec it because my car was from stock... not even sure wtf it does tbh.
I don't think the GTI/Clubby/R has side curtain airbags though without optioning it.
