Are you referring to this line?
It's called "red line" and it's there to indicate the unsafe RPMs zone for your engine, meaning that you shouldn't be revving at those RPMs or you may risk some engine failures.
In the past it was something to really keep in account, especially downshifting on a manual transmission; nowadays most engines and transmissions will automatically kill the ignition if you reach the red zone.
The red line has been on RPM gauges since the dawn of motoring, are you sure your previous cars didn't have it?

I guess they did so in order to adhere to the international standard of units. ml stands for milliliter and folks at BMW for sure didn't want that kind of confusion. Quoting from Wikipedia:
Quote:
Abbreviation
The mile has been variously abbreviated in English—with and without a trailing period—as "mi", "M", "ml", and "m".[4] The American National Institute of Standards and Technology now uses and recommends "mi" to avoid confusion with the SI metre (m) and millilitre (ml).[5] However, derived units such as miles per hour or miles per gallon continue to be abbreviated as "mph" and "mpg" rather than "mi/h" and "mi/gal". In the United Kingdom, road signs use "m" as the abbreviation for mile though height and width restrictions also use "m" as the symbol for the metre, which may be displayed alongside feet and inches.[6] The BBC style holds that "there is no acceptable abbreviation for 'miles'" and so it should be spelled out when used in describing areas.[7]
