Considering the scientific meaning of the word acceleration how could using the term acclerator when talking about a car's gas pedal lead to confusion?

When you push down on the cars accelerator, you are not always 'accelerating'. Sometimes, you are just pushing down to maintain a constant speed, because the engine wants to slow your motion down, that and the friction of your tyres on the road. Acceleration requires a rate of increase or decrease of speed. Hence the name 'accelerator' is misleading if your speed is not changing.
