6:22 The description of the situation is completely incorrect in some respects: while you are driving at 1600rpm at 80km/h with little power , there is not much vacuum, but there is almost none because the engine is turning slowly and there is no great demand for air. In these conditions, each cylinder produces 80-90% of the power it could produce at those speeds, i.e. the cylinder filling degree is very high and the combustion efficiency is high. If you then pressed the gas full, you would not get much more power. Under these conditions, the engine consumes the least fuel, but everything else you said is correct and not good for the engine.

4:46 Your friend should drive my car: in it you don't have to think about changing gears because it changes them automatically depending on how you drive, but the problem is that it still doesn't read minds, so I turned off the automatic gearshift. Now I change gears when I want to.
