LOL, true, but the actual differences are on a scale measurable by ordinarily used instruments is nil (doubly so in OSM). So from a practical perspective it doesn't matter. The differences in interpretation for a mile are rather more dramatic though (hm, me wonders if any croation/russion/swedisch/norwegian tourists have ever tried to get out of speeding tickets that way :) -- Cheers, Cobaco (aka Bart Cornelis)
