>That might be true where you live, but it's hardly a universal constant.

I have not said it's a universal constant, it's true in the US, where we use miles. ~1 hour per 100km is not as easy.

I cannot say I care much if you are doubtful, especially if you live in Germany and not in the US, I doubt many people in the US will care about your doubts too.

Even in the US I'm doubtful about 2 minutes per mile being true for actual "city" driving if you live in a bigger conurbation.
