yet another good point made, when the right foot is used for both gas and braking I suppose in some circumstances one could get confused.
actually when you first see the need to slow down the first responce is to let up off the gas, and then if need to stop then press the brake, we all know what works best for us,
but for some reason these small right or wrong things have been evaluated by our state patrol and the results put into drivers manuels,
this is just something I remember from back in my youth and studying for drivers exam , you are to use the right foot for gas & braking, their theory was that you have to remove your foot from gas to apply the brake theirfor will not be pressing them both at the same time, But things might have changed since 1974

the state drivers test might allow to use both left and right feet for each pedal,...................
hitekcountry, Let me ask you this----> if when driving a stick car and you come up on a hill and have need to stop, do you?
A- press the clutch in with left foot and try holding brake with left foot?
B- press the clutch with left foot and hold brake with right foot?
C- partly press clutch with left foot and feather the gas with right foot?
D-car floods and stalls out do you let off clutch to press brake with left foot?
E-or press brake with right foot keeping clutch press with left foot and then
try restarting car?
You will be graded on this
