As a VW owner, the nicest way I can frame my response is this. What in the HOLY FUCK is "accessory position"?
Note that I'm not exactly defending US made cars here. Being a US citizen and general car fan, however, I am nonetheless familiar with them. And your statements here are so mind-numbingly stupid that they deserve a response, if only to make everyone aware of what a holy fucking idiot you are.
The only kind of ignition switch I ever actually used has only off, on, and start.
"Accessory" is an ignition-switch mode in which things like the radio can be powered without the car engine or related subsystems (e.g. fuel pump) being powered. It is useful for sitting in your car after you've arrived at your destination, listening to the radio or waiting for someone to arrive. But then, you probably knew that, and wanted to impress us all with your vastly superior European-ness. Emphasis on pean-ness.
If the car is running down the road and I turn the key to off, no steering lock engages.
Reading comprehension fail. Go back and re-read the post you responded to. He did not say steering lock. He said power steering.
Yeah, the power assisted steering and vacuum assisted brakes revert to manual.
Have you ever actually driven a car where one of the power-assisted systems has failed? I have. I can assure you that it does not "revert to manual". Failed power steering and power brake systems are typically MUCH MUCH harder to operate than pure manual systems, and require enormous effort to control.
You have to use a little more force. BIG FUCKING DEAL. Any driver who can't deal with the loss pf power steering and power brakes at highway speed is a helpless twit and a Darwin candidate.
Since you seem to think it's not a big deal, please try the experiment for yourself. Get on the freeway, accelerate to 65 or 70mph (sorry, let me translate that to pean-ness: somewhere above 105kph) and then turn off the engine. Report back how it went. Go on, we'll wait.
