By default, Teslas are set in "one pedal driving" mode, which makes it so that the wheels won't turn without the throttle/accelerator being pressed. That's a different interface and behavior from the traditional automatic transmission, where simply lifting the foot off the brake pedal allows the vehicle to roll either forward or backward, depending on whether it's in D or R.
The selection of the "transmission" setting of P R D in a Tesla also doesn't have tactile feedback that subtly communicates which direction it's set to.
The combination of the two means that the car is different in these ways and can contribute to mistaken gear selection plus application of the throttle, compared to a typical car.
