I'm not going to get any love for this, especially from Tesla owners in CA, but it bothers me the emphasis Tesla is placing on supercharging CA at the expense of the rest of the country. CA already has an extremely large number of superchargers while parts of the U.S. have none. For example, good luck traveling anywhere in ID, NE, ND, most of NV, OK, AR, etc. There is currently no supercharger route between Gallup, NM and TX, or Topeka, KS to Indianapolis, IN. This list is not iall inclusive, but just examples.
I realize CA has a larger proportion of cars than other states, but I submit that Tesla will not significantly increase sales in other states until such time as they "wire" up the other states with superchargers. Even if people don't do long trips across state lines on a regular basis, they want to know they have the ability to do so, especially when spending as much money on a car as a Tesla costs. I have discussions with people all the time about this, and their primary objection to the Tesla is that they are confined to a limited region with the car. Most people are not willing to spend hours upon hours at an RV park to charge. I did it several times and its not much fun.
I submit that Tesla should use its equipment, crews, etc. to install superchargers along the entire U.S., and then they can proceed with filling in the "gaps" in CA. I truly believe this is the way to get the car to be more than an oddity in states across the U.S. As the saying goes, "build it and they will come". Build superchargers in every state of the U.S. and Teslas will be purchased in every state, not predominately some states.
No, I do not live in any of the states or regions mentioned in this post above. As a Tesla fan and a stockholder, I wish to see the appeal of the car and the company spread to as many people and places as possible.
