Actually steering is easier than shifting. The wheel can only turn left or right, whereas the shifter (or whatever it's called) can go into 5 or 6 different positions, choose the wrong one and you mess up your gearbox. If you're as right handed as I am, you'll have a hell of a time shifting with left. Therefore, the right hand should do the shifting (for right handed people of course)
Drunk driving is poopy.
Indeed, drunk drivers are even more stupid than most regular ones (playing with the radio, putting on makeup, phoning).
