It seems to me that the metric system would be easier to scale down using 1/25 as opposed to 1/24 and 1/25 or 1/24 would be compatible on American cars depending on whether the cars were designed using the decimal inch or the fractional inch. Just curious.

I'd like to know that too.
I bet Hiroaki knows the real answer
