While the use of the Kannada script (but not on number-plates) does certainly contribute to the propagation of the language and thereby the culture, the numerals do not serve any such purpose at all. The regular 1,2,3 can as well be read ondu, eradu, mooru, so on, without in any way diluting the purity of the language, but in many ways simplifying life, particularly for the non-Kannadiga's who then have only to grapple with the jalebi's, the prospect of which is less intimidating.
