DFCO is very common in modern automobiles.
The fuel cuts back in at idle power level when the engine speed gets down to some preset level just above idle.

Hmm you said "turn the (ignition?) switch" off. I agree it would stop. But we're talking about taking your foot off the gas pedal and supposedly the fuel is cut off. If I took my foot of the gas of my Yaris it would slow down sure. But it would eventually go about 5 mph, not stop.
