If it does that would help...

Weighing it down gives traction. Hell, most hillbillies load up their truck beds in the winter because the weight is such a big help, especially in the back.

I think I might have heard something about weight distribution though, like a normal truck has an engine over the front, but Tesla's weight is in the middle of the axle.

But this is the tires, and probably something about whatever this things equivalent to a transmission is. Like you only need to put your foot on it a little for normal driving. Which means take offs in snow would almost always spin out.

So like the RPMs of the wheels go up to fast? I think that's the easiest way to say it.

It makes a vehicle seem faster the less you have to push on the gas pedal, it's a pretty old trick, because most people never floor it, so they don't notice halfway thru it stops doing anything.
