This is an important point as cars nowadays have more and more electronic overrides - everything from traction control to stability control to anti-lock brakes to lane departure warnings (and recovery) to emergency braking and speed control.
Most of the later ones (emergency braking, speed control, lane departure) are only on expensvie cars, but within 10 years will be standard equipment on all cars. If not by legislation, probably by insurance companies offering discounts on vehicles so equipped.
It's already an issue with ABS braking in that people run into things even though they could steer around them - simply because they become fixated on pressing the brake harder and harder rather than trying to steer the car away from the impending object.
As people learn to drive with these aids and rely on them, they will become dangerous when one or more become faulty. I can see a point where people start to rely on automatic braking and don't bother putting their foot on the brake. Or take their hands off the wheel on the freeway because the car keeps it in the lane for them.
All this is great until something stops - a camera gets a squashed bug, a wheel sensor breaks from a stone, anything. And the car will be under partial human control and the inputs will be badly exaggerated.
This will become a large issue in the design of vehicle interfaces and driver training in years to come. The solution, of course, is mandatory emergency situation training in an unassisted car. But driver training is routinely ignored worldwide for cost reasons.
