As a driver of both types of cars, this is completely false, in my experience. Having a clutch pedal doesn't make drivers more aware or capable. On the contrary, it's a small cognitive load that can be freed, then put somewhere else. A bad driver isn't thwarted by a stick shift. They'll do the bare minimum to keep the car on the road. These drivers are notoriously bad at selecting gears, so they usually solve that issue buying diesel-powered cars with a more forgiving power curve.
