Variable ratio steering

Just been reading something about EAM version coding, and it said all vehicles except right hand drive are equiped with variable ratio steering. I have thought for years that i was driving a car fitted not with wheels but planks of wood strapped to the rottors like ski's. Feels like wood with far too many turns. If you go from full lock to the opposit lock it is massive amount of turns, and in tight spaces lethal. So what has you car got that mine hasn't?. I have a ford transit van and that has the best steering of any car i have ever driven. First 3/4 turn is normal, and the next half turn is like turn and a half. Enough to throw you out of your seat if you have no seatbelt on. Brilliant. How many turns does a USA ml have from centre to full lock.
And also when i see a w164 ml for sale in england, it say united kingdom steering in the vehicle specifications. Are we getting something different?.
