It doesn't explain why the fellow in
post #64 is able to accelerate from 60 to 110 km/hr while that warning message is being displayed and his foot is on the brake to some degree. Shouldn't reduced motor power prevent that kind of acceleration? Yes, he could press the brake harder but
the point is he is pressing the brake and the accelerator, the car notices this, and yet the car accelerates.
The commonly held response if you look for "Tesla brake and accelerator at the same time" seems to be people feel that the car will not allow it, and the car will come to a stop. However it seems that in various cases it does allow both to be pressed - with various different responses depending on the situation.
In other words we are back to the beginning of the problem with the brake and accelerator being used at the same time.. The car decides whether to override the driver's foot on the brake, and in some cases it allows acceleration.
Thus brake pedal + accelerator does not always kill the motor nor even does it always reduce the motor, in fact... it depends on speed, amount of force, car mode, etc, sometimes it will even accelerate.
Now we have nullified the safety rule of "driver decides" and we're back to "the car decides".
