I might just jump in the driver's seat and take over

And that would have worked. That brake pedal is physically connected to the wheels.

I heard that some EVs have enough torque to overcome brake friction if it really goes all out. Anyone knows is that true?

That might be true for some of the extreme performance EVs (Rimac Nevera: 2360 Nm, Lucid Air Sapphire: 1940 Nm), but I think the mechanical brakes can probably overpower the 700 Nm of Waymo's Jaguar I-Pace.

I read that Model S accelerates at more than 1g and I think it has 1000 nm of "instant torque" from zero. Roadster has 10000 nm. They say top notch mechanical disc braking can decelerate at less than 1.3g tops. Should be enough for 700 nm but seems like even many consumer grade EV literally can't stop with your foot if electronic brain doesn't cooperate.

The maximum deceleration is the traction limit of the tires; most braking systems on cars have the mechanical ability to exceed it, which is prevented by ABS on modern cars. If both the motors and the brakes can exceed the traction limit, as with the Nevera, then we don't know which is more powerful.

As an aside, spurious ABS activation is a form of runaway car automation that has been possible for decades. It is terrifying to experience.
