May have been mentioned before, but Yuma to El Centro is only 60 miles. But, I don't know the logistical problems in spacing SC's in that area. It may be a question of either too far or too close where too close would be better.
Electrical availability may be the defining decision.
Terrain to the west of El Centro may be the reason, I know that gas mileage goes down a lot over that segment so it may be tough to do Yuma to SAN in a 60 without El Centro. Also since the most southerly supercharger in California will be San Juan Capistrano those traveling I-8 to I-5 North etc would have a problem.
Going East you might be going to Tucson, hence (I guess) Gila Bend.
Now I'm hoping they put solar panel canopies over these stations by the summertime Yuma's HOT
