I live in Denmark where hour is time so it is called km/t.
In the International System of Units the symbol for kilometre is "km", not "KM", regardless of language. The symbol for "hour" is "h", regardless of the word commonly used in the local language for hour (which I now know is "
time" in Danish, spelled like the English word but meaning a specific unit

.... and pronounced "teem"). Using "T" makes sense to you and it's your car, but using non-standard symbols for standard units is not good practice in general... and even if you prefer the "T", I think using the lowercase "km" would be better, to keep at least the "kilometre" part using the correct symbol.
By the way, "T" is a valid symbol for a unit... the tesla, the unit of magnetic flux density. So "km/T" would be "kilometres per tesla".

Ironically appropriate for an EV, but still physically nonsense. The lower-case letter "t" is not a unit symbol, so I suppose that "km/t" for "
kilometer i timen" wouldn't be so bad.
The yellow and red are because it was made such original on datsun z.
You can also see my speedometer at the top of the thread there is a line from 100km / h and up

Okay, I get wanting the authentic marking feature. It makes no functional sense so it would annoy me, but I suppose it's harmless... and of course it's your car!
