I can vouch for this, my first time driving an automatic was a mustang in America on the "wrong" side of the road!Don't worry, it only takes one incident of retrieving your teeth from the steering wheel for the penny to drop.
My car is a manual, my wifes is an DSG.
I enjoy driving both and adapt instantly with either, but personally wouldn't own an auto without flappy paddles; I think they are more engaging to drive.
