If I get in a car, I expect consistent behavior based on previous performance. If the car pulls a "I'm sorry I can't let you do that Dave" and arbitrarily changes behavior when it feels like it, bad things are going to happen.
In most cases, I'd rather lose control and slip and slide around on/off a road than get flattened by a long vehicle merging into my lane because my car limited my acceleration.
That is an absolutely insane position to take. How about instead of losing control and going off the road, you take the car off the road in a controlled manner. You're already okay with going off the road... so just do that in case you find yourself in an exceedingly unlikely situation in where it's needed.
Otherwise, I'm not buying the whole "pedal to the metal is going to save me" line.
Anecdotal as well, also with a huge grain of salt, considering that despite being somewhat old, I'm only allowed to drive since December. To other drivers I'm probably overly cautious, I guess.
