Wrong, irrelevant and morbid.
Tesla X, and any properly created EV propulsion for that matter, can't be really judged in term of any antiquated 4WD system as it does not have any of old technology shortcomings.
Strange delusion, considering ICE tow vehicles have been up to the task for decades.
There are no shafts, torque converters and clutches that lose time switching among themselves to transfer what's left of the torque.
There is no loss of torque issue, mainly how much traction the tires achieve. If anything the driver couldn't modulate the torque well at all, based on the tire spin.
Milliseconds matter when you are uphill on ice.
Not much. Winter tires matter uphill on ice, thought that wasn't ice, and you're wrong about milliseconds. ICE vehicles have had millisecond sensing for years and less rotational wheel weight to reign in.
Plus any reduction of wheel spin on the tesla is necessarily the wheel reducing torque, except it's the opposite, your whole argument falls apart when you see in the video that it was continually
spinning its tires.
In short, any random 20 year old clunker 4x4 SUV with winter tires would've gotten that semi up the
hill very slight incline faster, and would've been better suited to winter tow patrol due to more ground clearance.
Most AWD ICE sedans of equal weight and same tires would've done about the same if you just threw enough weight in the trunk to equal the X's greater weight on the rear wheels.
This is a different situation than non-towing, taking off on a straightaway where momentum can be achieved with minimal traction loss.
