I don't know if it applies only to Europe, but I know I've never seen a car in America (even the European imports) with the tachometer numbers abbreviated to the tens place. In America, it's abbreviated to the ones place. If you don't know what I mean, here's some pics. The first is American style, the second European. And if you know what style other places in the world use, I'd like to know that too.

Obviously, neither way is wrong. But if one is going to abbreviate a long number like 5000, why choose 50 instead of 5?
I guess while I'm on this subject I can also ask why European fuel gauges show full and empty as a number (1 and 0 respectively). Sometimes it's even a fraction, like 1/1 representing full. Anyone with even the most basic understand of math would not be confused by this, but it still seems unjustified.
Anyway, I don't expect many answers on this. It's probably an unknown. But hopefully, the right person at the right time finds this. Thank you in advance
