Anything "By wire" means that specific control gets its inputs through a wire. There are many aircraft that are going that way. Using wires, instead of a mechanical, hydraulic or pneumatic link to the controls.
Drive by wire is just kinda the term thats been used in the auto industry, but is not literally Drive by wire. Drive by wire would be something to the effect of a joystick/buttons that control every aspect of controlling the car.

Toyotas that can park themselves (mostly) are DbW.

You misunderstood what I was saying or maybe I did not state it clearly enough.
When a Toyota is parking itself, it IS DbW. It does not matter what the steering wheel is doing while it's doing it, it could do the Waltz and it makes no difference, it's still DbW when parking.
Unless this guy pops out when you auto park it, it is parking itself by wire:
And I did not mean that it was mostly DbW, I meant it mostly parks itself.

While sensors and computers are driving the vehicle to that spot, I dont think that the car driving itself qualifies as DBW. Just like cruise control is not drive by wire.
MAYBE park by wire
I think that the term DBW is really interpreted differently, and its actual definition varies when applied to aircraft, cars, boats, whatever.
However, no matter what platform we are talking about DBW typically mean REPLACING the mechanical link between the driver and throttle/brake/steering wheel/rudder/etc. Its not just automatically controlling something that is otherwise mechanical.

Then why have an accelerator that simulates the "feel" of being mechanical when it's really not?
Just for tactile feedback to the driver to make them feel like they are actually mashing it down and yanking that throttle plate open?
Would that tactile feedback not be the same thing as the toyota steering wheel turning when a computer takes control?
Might as well have a PS3 controller in there
If I were a marketing genius, I'd call it an emergency recovery system in the unlikely event that the DbW system fails.
Of course, we're probably rapidly approaching the "pointless debate" pits of despair...
Probably what it will all boil down to is that it's not properly defined well enough or even implemented broadly enough to say that anything street legal is really DbW yet, maybe in 10 years.

I know there was some mercedes and im sure a handful of other concept vehicles out there that were DBW (in all aspects).
It would be pretty wild to all of a sudden say "this years S2000 is DBW, so instead of a gas pedal, you will have a throttle control lever on the steering wheel that acts as the accelerator". MUCH easier to make the standard gas pedal feel like a standard one with springs and whatnot as to change the way we have been driving cars for years.
Thinking into this a little more, I'm guessing a major hold up of true DBW systems is that it would not make sense to have the controls as we know them. It would be easier to have a joystick or a PS3 controller work our cars... However I would imagine that would affect the billions of people that currently drive, and have to educate and license ALL those people that grew up on the old system.
Even in aircraft (where each pilot is trained extensively in the exact aircraft he flies) they try to retain the way the controls feel and operate, just imagine in a car...where someone who may not have had a road test in 40 years get handed a controller!
