“The truck’s brake didn’t disengage the accelerator pedal.” So the driver did indeed stomp the gas. Why is this even a headline.

Cybertruck had a problem with the gas pedal faceplate sliding up and locking the pedal in the full throttle position.

Are you saying the car should go if you press the accelerator while you're holding the brake? No car I've ever driven worked that way, if I'm holding on the brake and I apply pressure to the accelerator the car stays still.

  Right - it's how Audi's "pseudo" launch control works. Push the brake pedal to the floor. Push the accelerator to the floor, and then push it past a last detente while the ECU holds it at 3500rpm and builds up the turbo boost, and then you can release the brake. You can feel that the brakes are what's holding you, but never do you feel that they're about to fail and you're about to floor ~520hp unexpectedly.

  Then how are burnouts accomplished?

    They're accomplished by having the more powerful front brakes hold the car while the less powerful rear brakes allow the rear wheels to spin. Sometimes water is used to reduce traction. Sometimes the brakes are modified so that the front axle can be controlled by a hand lever without applying the rear brakes. In this case the Tesla was able to overpower its more powerful brakes and drag the car forward. That should never happen.

    Did you know cars generally stay still during burnouts?

Maybe because electric vehicles don't have gas to stomp on.

  It's pretty obvious they were referring to the accelerator pedal

If the team writing the Cybertruck firmware was confused by - user has depressed brake - user has depressed accelerator ... and needs to pick a priority between these two inputs, I am available for consulting.
