I'm curious what that button does? Does it go full "emergency brake" mode and stop the car ASAP, or does it give control back to the driver?

I could see the former being useful during development, but I wouldn't want a "slam on the brakes" button in my car. And the latter could be much more easily worked out by just switching under any driver input on the steering wheel.

I work in the automotive industry for a manufacturer. All of our prototypes have big emergency stop buttons in the center console using 3D printed adapters to slot into the cup holders.

They just kill the engine and disconnect the battery. It's a legal requirement. Nothing fancy.

So if you are at speed, the car starts engine-braking (with no proper brake force distribution between front and rear wheels), and the power steering isn't working, right?
