Popping into neutral would cause the engine to over RPM, and potentially destroy the engine - turning the ignition off simply shuts the engine down ... something that is inherently obvious to me.

All of these new computer controlled cars have rev limiters to prevent the over revving of the engine. He'd have been better off to keep power (for brakes, steering, etc.) and just slam it into neutral.

Escatly...never turn off the engine or you are sure to lose control of power steering and power breaks. No engine, no ‘power’ and a locking steering wheel.
