Master battery disconnect which auto locks all brakes

Plug and play ROM modules?

probably want to separate those. Kill the engine at 80 mph, you can coast to stop. If you lock the brakes at 80 mph, you immediately lose most of your control, and, since you killed the battery, you lost traction control and probably ABS. And you risk blowing the tires.

Maybe one day the OS will go rouge and we will have to start pulling out memory modules to save ourselves

Interesting. Instead of just an emergency brake, you want a second emergency handle: a mechanical linkage to a circuit-breaker on the mains.
