Not a Model S owner, just obsessively following Tesla and the advance of EVs.
With enough sand/gravel at the bottom of each freshly dug hole, these become virtually frozen-ground heave-resistant.
They already have the conduit cast in-place with the holes for the two stanchions.
And mounts for lifting rings.
Flexible type conduit at the ground level makes hook-up more adaptable/easier.
Precast makes everything much easier/quicker to install.
No need for concrete add-mixtures for very wet or very cold conditions, just a bit of cost for shipping and installing the pre-cast/fabricated units.
Oh, and they could be re-used and re-positioned at a future date should a change in layout be required.
Maybe they could start using these in U.S. Supercharger locations?
