I was watching this video of a live chicken trapped on a moving truck and thought it was strange that it’s not possible to say anything to them even when circumstances might warrant it. All we got is honking and waving. There could be a touchscreen interface with a map of nearby vehicles. It could be voice controllable or the passenger could do it for safety.
Or we can stick to kph for discussion purposes, since that’s what most of the world uses
Sigh… Everyone is used to what they have used all their life and refuse to learn anything else…
Is there a reason why people on the metric system have a need to be learning imperials? (I know 1 mile = 1.6 km, but that’s another matter)
What does anything matter. If you deal with someone else at least one of you needs to learn the others systems. You and your neighbor probably speak the same language so it is easy, but the more differences the more there is to learn. You can choose to not deal with people in the US who only know US systems, or you can work with them by learning. I have no idea what your motivations are, but whatever they are they becomes your reasons to do or not do something.
