Wheel PCD and hub size.
If every car and (light) truck had a 5x114.3 bolt pattern and a 66mm hub size we could swap so many wheels around. It would be amazing.

Electric car chargers.

This is the direction the industry is going to go. F#kn standardize it already, with a reasonable future-proofing schema that handles various voltages, and puts out what the car specifies.

Music teaching, we should use the Kodály method everywhere (where it's applicable)

But if only one thing, the hand signs (solmization) should be standardised by how Kodaly imagined it; a relative solmization system with all the 12 notes.

I just can't understand why everyone is focused on the absolute naming in music, absolute distances etc. when all of this can be easilly done with relative solmization. (and, when you need the absolute names or distances/values, you can just put the whole thing in context by just defining "where's the dó" and then you are set.)

That there SHOULD be as many standards as possible!

Que speed, the one you're in is always the slowest.
