You are looking at a car driving on a hilly road.
The car&#x27;s engine is not powerful enough.
You observe that on the uphills, the driver is flooring the gas pedal and yet the speed of the car is decreasing.
Confusing correlation and causation leads to the faulty conclusion =&gt; the gas pedal must really be the brake pedal<p>Enabling (arbitrarily) negative rates is equivalent to lifting the power limit on the engine and would simply allow the driver to keep the car at constant speed on all hills (the brakes already have unlimited power)
