Well ya, because you do drive off road lol. But Let's say mrs money drives an auto BMW, left foot brakes and has all her life. Husband buys her a stick shift, second she goes to hit the brakes she just pushes her left foot in, habit, car doesn't stop. All she did was hit the clutch.
Friend of mines mother did this, drove a stick hit the clutch instead of brake out of habit and was in an accident.
Kind of an obvious example of inexperience and inattentiveness.
Grew up with both, driving auto/manual in their respective ways. I guess it's a mindframe and putting yourself in a vehicle to do a job; not just sit there and do things by route.
I also tend to drive a lot of different vehicles, so its like going through a mental checklist for whatever I'm driving.
The biggest thing with a manual; you stomp both feet during a panic stop. You can never go wrong if you use both feet during panic braking (one clutch, one brake, simultaneously).
