Given that the accelerator pedal now only operates a potentiometer and
autos don't bring mechanical connections to the driver, there is no easy
way of knowing what a "stuck throttle" fault is and how things are going
to respond to the driver's random fiddling. The foot brake is a known
quantity and the only system with sufficient independence.

The footbrake will also (hopefully!) cancel cruise control. Being cynical,
that is one cause of supposedly "stuck throttle" :-)
