Push button start
Been wondering ... with push-button start (I think we call it "Keyless Go"?) is there a way to turn on accessory power to open a window, listen to the radio, etc. without starting the engine?

That seems really odd. I don't keyless go in my Mercedes, but I do in another car. All accessories turn on when you enter the car (with the "key" in your possession). No need to press anything. It would be odd to have to press the button twice to do the primary function, which is to start the car.

OK...so name the car. I have NEVER seen anything that will turn on all the accessories without having to first press a button.
Think about it...this would mean you can never leave the keys anywhere near the car since it'll never shut off.

The car I'm referring to is a Ford Fusion Hybrid. And the accessories do not come on simply when the key is near vehicle. It's a combination of opening the driver's door, having the key, and possibly sitting in the driver's seat. I only drive it occasionally, but I'm fairly certain this is how it works. Because I can never tell if it's running or not. When you get in everything is on, dash and display lit up, etc. And since it's running on the electric motor, you cannot tell that it's running. I finally figured out there's a little light on the dash with a couple of arrows that indicates when it's running.
Conversely, if you exit the car with the key and close the door the vehicle shuts off. If the door is open you can walk away and the car will keep running.
Again, that wasn't my point. My point is every car I've owned or driven with a push-button start only requires your foot on the brake and pressing the start button ONCE.
But, this is Mercedes, so who knows WTF they do. I see these very elderly people driving them and assume there is no way they can figure out all the features. Much less program the garage door opener.

My point is that is seems odd to have to press a button twice to start the. That's not logical, as the primary function of the "start" button is to start the car. It's not a secondary function.

As for accessory power, It is no different then having a key. With a key, there is still 2 positions.
