Thank you, now that makes perfect sense :)

Isn't the rack-and-pinion for steering, not for power transmission to wheels?
Yes rack and pinion is for steering. Parent may have meant "ring and pinion" which would refer to the differential gear ratio.

Yes, you're right of course. Thank you.
I was wondering, because I seemed to connect the expression with steering as well :-) At least I have the excuse of not being a native speaker.
After gearing, you'll have the same order of magnitude torque at the wheels as the Tesla.
Randomly picked example: Porsche G97/01 (997 Carrera 2 2005-08) First gear total reduction 13.45 (gear 3.91, rack&pinion 3.44)
So, ignoring efficiencies, you'd have a first-gear torque of 400Nm * 13.45 = 5380Nm at the wheels. Still "only" half of the Tesla, but not an earth-shattering difference anymore.
