Trouble is generally there is an official answer and the real answer to such questions. There is strong evidence, for instance, that the Wright Brothers were not the first to achieve powered flight. They were the first to gain international publicity for achieving powered flight. Not the same thing.
Still the fun is to see if the grey matter can produce an answer, before looking it up and finding the answer, and then submitting it before everyone else. My knowledge on odd cars is not as good as people think. Partly because I find I only really memorize things I can use on cars I have. I forget about stuff I read that is not directly useful. Annoying, as when the answer comes I think to myself. I knew that, but could not bring it to the front of my mind.
Bit like IQ tests. I find I start looking at the questions and think, 'but who cares'. Allegedly I am capable of a high score but what does that actually mean? Perhaps thats why people have no idea what I am on about half the time as I am a sort of moving IQ question to other folks. That works well then, especially as I make as many mistakes as other folks! Maybe I should do yogi or something. Yogic Bubbling, increasing the reliability of your unknown microcar, as you obtain it.
