As long as you don’t push the accelerator pedal down too far its okay. With the car in say 5th or 6th gear, the engine is turning at very low RPM’s. When you push the gas pedal down too much, the engine cannot take in the amount of air that its trying to force in to it, because its not spinning fast enough.
Some of the airplanes I use to fly had 2 levers in the cockpit. One controlled manifold pressure (throttle), and the other controlled engine rpm. Having the engine rpm lever set in a low rpm configuration, along with a high manifold pressure setting was always considered to be a bad practice.
