My posts go way over the top of most peoples heads. They just don't understand.
Did you actually understand that link about the weight saving??
To go slightly OT here, yet another example of how car "culture" becomes more of a religion than a science.... just because somebody wrote something that doesn't make sense but was written by someone who has some sort of authority... people are frightened to question it.... in case they are made to look silly.
Everyone makes mistakes... sometimes on purpose, to get a response.
Then of course somebody else will repeat what they read, again not understanding what they've read but it must be right because it was "on the net" and written by someone they have confidence in.
