Maybe, once upon a time, there was some logic in allowing the engine to idle before driving, but with today's engines and (in particular) the high quality of modern engine oils, I don't think this is a problem. So, I wouldn't idle the engine UNLESS the manufacturer's manual specifically recommended it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
