Comment Re:Remove keys from ignition? (Score 1) 1176

I've never understood why cars and the like don't have fuel cut-off mechanisms available to the driver.

The few boats I've been on had - they was a tag/cord you could yank, and when done it would physically block the fuel line.

I could see this as being one of the first things that could be done after a major accident. Yank the handle, chances of a fire shoot right down.

You don't always have a discrete pump, it could function from sucking pressure from the mechanical injectors (which could be driven by the gearbox... driven by the engine). Only the real modern (and expensive) engines are driven by electrical control.

This is one of those reasons they have governors. Without it, the engine would runaway and destroy itself, as more engine output means more fuel draw which means more engine output etc...

My car has:
OFF, ACC, ON, START

The engine starts on START, obviously. The key sits at ON while driving. If I drop it down to ACC, the engine dies but most things stay powered. The wheel does not lock.

The wheel only locks when I move the key to the OFF position, and to do that I have to be in park or neutral (or use some kind of poking implement to depress the shift-lock override, which also lets me do Bad Things like drop it straight into park from drive.

Every car with a key that I've ever seen has the same configuration.

This is clearly another case of too many mad scientists, and not enough hunchbacks.
