If you've physically started the car by being in proximity of the sensor and pushed the start button, then left the car, I suspect it will continue to run even if you put the keyfob somewhere else away from the sensor.
My IS350 does this...if you start the engine with the keyfob but put the keyfob outside of the car, you are still able to drive the car regardless.

I think what we're missing here is the consideration of a dead battery in the key fob.

If they decided to implement a kill engine switch whenever the car is unable to detect the key fob, that would mean running the risk of an engine stopping dead on a freeway because of a dead key fob battery. That would be pretty scary imo. Who knows, maybe the engine DOES turn off when you try to drive it without the key. I kind of doubt it myself, but I'll try it when I get back home.
