Ok, here's my solution to lifting a Tesla for seasonal tire/wheel changes. [I would not use this for working under the car, though].
I bought a 2-ton RakJak pneumatic lift (see:
RakJak™ 2 Ton Double Bag Air Jack)
I got mine on ebay a week ago when they had that 20% off sale:
Unitec DBT2 RakJak 2 Ton Pneumatic Jack 69060287622 | eBay so I paid $365.
You also need a small air compressor. I use this Dewalt model:

Plus
@Murphy’s Law lift pad adapter. (paid $40 plus shipping)
The RakJak comes with it's own jack/saddle pad, but you can see it has these little 'crown' type ridges..

... which actually makes it too high to fit under the car with the ML lift adapter (with SAS set on maximum height)... so it's removable, and I just use the flat plate below it to lift the car -- the weight is spread evenly over the entire jack plate and the lift adapter.
Here's a quick video -- I lift the car just enough to get the wheel off the ground for changing. The lift actually goes much higher. This is much easier than rolling a floor jack around, and having to manually pump it up and down.
Once the car is lifted to the proper height, the compressor will stop running -- it's only running to reload the 1 gallon air tank and not keep the air jack lifted (it only appears that way).
I will get a block of some material (a 2x4 or hockey pucks?) to fill the initial gap between the lift plate and the lift adapter, so even if the air jack fails, it will fail safe and still hold the car without a wheel off the ground with no air pressure at all.
