It's no mystery. If they can't get a permit due to local politics, there is not much Tesla can do.
Except that's not the whole story. As we know, ~600 days ago, they had a permit application, which was allowed to wither and die (the culprit having been assumed to be local resistance). Since then, numerous other West Texas SCs have been hatched in spite of politics, local and otherwise.
Instead of relying upon one overwhelmed fellow based near Phoenix for further Texas expansion, the Supercharger Team has enabled a new fellow who is based in Houston. While not quite West Texas, at least he's in-state, and in a part of the country where face to face and local relationships matter, that can only help. This was part of the whole quadrupling of the team thing and of course they're not done yet.
The delay in execution has turned Fort Stockton, in my mind, into a Top-5 GET THIS DONE NOW challenge. I-10 remains the safest way to get from Florida to California year-round, relative to hanging a hard right at Houston into tornado and black ice country along I-40.
Thinking outside the box, would it be possible to solve California by partnering the deep pockets of major auto companies and having them lend a hand in a more rapid expansion?
While I'm all for thinking outside the box and tilting at the occasional windmill (see West Texas above), here's the thing about what I'll call the Challenge of Coastal California: We haven't quite yet hit critical mass for the deployment of charging stations and networks. You get the impression that it's coming, but it ain't moving at maximum velocity. You don't see, for example, the same success on the part of AeroVironment in SoCal that they had along the Oregon Coast with their ChaDeMo/L2 installations at grocery and other locations including at least one Chevron gas station - for $20/month unlimited usage no less. I don't know what it's going to take to get to the tipping point hereabouts. Rumor has it that Dieselgate money has finally manifested itself in a first phase of 160 sites, 40ish of which have been confirmed. Well, okay, ,but what of the 12,500 chargers from the major utilities? Plus the Tesla buildout. That, collectively is a lot of real estate to lease and develop. If the other manufacturers want to jump into that morasse then more power to 'em, but I'm not sure (other than placing single L3/L2 couplets at their stealerships (see Nissan) for business hours-only usage) what value they'll be able to add.
Now, a partnership with the oil companies could have legs. Target the majority of properties that have the space for at least a couplet as referenced above and that's a good start. Those that have more space might opt *gasp* for a 4-station option. You'd think if there's an L2 charger 125 miles northwest of the Edmonton, Alberta SC (and there is), that a concerted effort could get a number of gas stations lit up in SoCal. Heresy, I know.
One point of amusement lately has been at the newest/flagship Costco in the South Bay (Lomita/Torrance). They've got maybe a dozen L2 chargers adjacent their food court toward the back of the building. They're never all full - even with ICEs. Across the parking lot would be the sizable gas station area - routinely with cars spilling out into the roadway blocking traffic, horns honking, the works.
All in good time.
