I rode in a P85d or P90d, I can't remember which one.
But the initial launch is HARD.
There are a few reasons, not all of which is Torque.
First is the torque. Electric motors develop max torque from 0rpm, and it falls off after that. This is why they have relatively good acceleration, but crap top speed compared to a gas engine.
The 2nd reason their acceleration is so good is the speed of the electric motor's response to throttle requests. The Traction control system can switch the electric motor on/off incredibly quickly. Hundreds of times faster than an ABS system can actuate a brake to control wheel spin.
This means that the Tesla can literally put JUST the right amount of power down for acceleration regardless of traction. It can react to wheel spin so fast as to make it seem that there is none to human eyes.
Watch one take off, the wheels hardly spin at all even in slow motion. Thats because the controller is managing the power that quickly and precisely.
So you get a huge pool of torque to apply, and a system that applies just the amount needed for maximum acceleration.
End result? If you were not paying attention and had your phone up by your face, you'll make yourself in the face with said phone.
