Actually the same argument could be applied to your observation of the driver to vehicle interface. You say "brake petal" simple because it controls the brakes. Well then what does the "accelerator" control then? Most wise observers would blubber... "I know, I know, it controls the gas!"...and while partially correct they would be mostly wrong. Yes it does control the "gas" but not in a direct way. Of course technically it depends on implementation (a favorite word around c.l.py it seems *rolls-eyes*). In the days of carburetors the "accelerator" actually controlled a big flap. This "big flap" (An attribute of which many round here seem to posses and use generously) is opened to allow air to enter and the gas is mixed into the air by secondary effect. So if we really wanted to get pedantic we should call it an "air petal"? However considering that any vehicle made after the early nineties is fuel injected (which is controlled by a computer!) then we may want to call it a "puter petal" to be precise.
