A blank piece of plastic. That was obviously well thought out in advance.
Oh, wait! It's different between the Escape and the Escape Hybrid. Wow! That's intuitive. On the Hybrid, there's a cancel button. On the non-hybrid, there's a blank piece of plastic, and you tap the brake pedal to cancel.
A blank piece of plastic... which design is the cheap one? The one that doesn't have a separate button, or one that used to, eliminated it, but didn't get rid of the blank piece of plastic where the button used to be?
I think it is sensible to have the same button do multiple things, pending the last state. Do you have separate on and off buttons on your Ford radio, or do you press the volume knob once to turn it on, and again to turn it off? AM/FM/FM on a single button? preset #1 for three different radio stations or a CD selection?
Functionally, it's whatever you're used to. A friend thought that his Oldsmobile, with reverse at the rearmost position on his console shift, was perfectly intuitive, and couldn't figure out why it was mandated to move to a prndl layout.
