should I learn stick shift or auto? (stick shift is manual) (my dad drives an auto and wants me to use my right foot for brakes and I hate it, (my left foot is dominant and its much more easier and comfortable))
If you drive stick you'll still use your left foot to brake... reason being you'll never brake and accelerate at the same time, but you might need to brake + clutch or accel + clutch.
Also, if you're driving auto, you'll react faster if you only use one foot (be it the right or the left one) since you'll always use that one foot, there's no time wasted in deciding which foot to move, only where to move it.
By far the worst option when driving auto is accelerating with one foot and braking with the other.
