I seem to remember a documentary where it was reported, or even recorded, that Spielberg asked his son 'what was a cool bike' and the answer was 'Kuwahara'. I have that memory and have nothing more to back it up with, nothing.
That said what would the director's son say today, given we are so many years on? I do not know, I am stil stuck in 1982 but others may be able to answer the question: '..what BMX is cool?'
