An automatic transmission is effectively decoupled when the engine is off despite being left in drive. Without the engine spinning, there's no functioning torque converter. So the most ubiquitous ICE configuration, the auto with a torque converter, defaults to a neutral equivalent when the engine is off and the operator doesn't explicitly put the trans in park.
