Cybertruck Parking Brake - one system or two?

[speedstuff]

I understand that there is no physical parking 'pawl' in the Cybertruck.

So my question is when you park and walk away from your CT, what is stopping the truck from rolling?

Sounds dumb I know, however I ask because I also can hold my finger down on the 'P' selector on the screen and then 'hear' the electric brake in the rear operate AND an additional 'Park' indicator pops up in the screen.....

I think it just applies the disc brake pads on the wheels, when you put it in park you can see the pedal depress

" The Cybertruck's parking brake is an electronic system that automatically engages when you shift to Park, using electric actuators on the rear wheels for a secure hold, and disengages seamlessly when you press the accelerator or shift out of Park. It's integrated with regenerative braking, uses the main hydraulic brakes if needed, and can be manually activated by holding the "P" button on the stalk or through the touchscreen for added security, especially on inclines."

I just know that when I'm on steep inclines 007 senses the incline and seems to brake even harder. I can feel it from the seat get stronger on inclines. It also makes an audible "pop" when I re-enter and put it in drive. There are brake settings as well from the touch screen menu under "Safety."
