It probably be a few year before the the factory stood up. If it does happen, hopefully will be more SCs.As I understand it Tesla will likely be be setting up the next factory in Austin. Think you will see a lot more Teslas in Texas as a result so I would only expect charging to get better. EVs are becoming more desirable as well so charging options should continue to expand. As I mentioned my husband has always charged away from home, and he has a 75kWh battery pack in his Model S. Until a SC stationed opened closer he was sometimes driving about 10 miles from home if he wasn’t out during the day and charging while on the road. So 5 miles isn’t bad. Besides you will probably find yourself looking gor reasons to drive your car!
A few of our public garages and shopping centers have chargers and I see cars rotate out of the spaces during dinner hour when people would drive downtown for a meal and charge during that time for some extra range. Expect that will be true for your area as well. 20-30 extra range miles while shopping or dining for an hour or so is nice if you aren’t driving long distances all the time.
Let me know if you want the referral at some point. Given what I know from my husband’s charging, I don’t see your area as being something that would concern me about not being able to charge now or in the future though.
The thing I like the most about EVs especially the auto pilot. Last time I drove a Ford Edge with ACC and Lane Keep Assist, that 4 hour drive was a breeze. That's why I'm so looking forward to have one.
