I encourage you to hop in your car and try to drive to Nashville and then see what we are dealing with. I would like to go west from Nashville sometime before my battery warranty runs out. Maybe even drive to Napa?
See, that's the difference. We never expected any superchargers. And when they came, they were icing (not ICEing). I was reading below your post, where an owner was "not able" to get to Nashville from St. Louis, and yet many of us ARE able. It just takes longer. I guess if I had been "promised" I would have superchargers between everywhere to everywhere, I might be upset, but folks, they are working on it, don't you see?
This is not GM. This is teeny tiny Tesla. Oh, and by the way, GM doesn't have any plans to build out a charging network, either!
I got really good at driving slow and stretching my range a couple years ago. I would love to try going from St. Louie to Nashville, or Nashville to St. Louie, and I bet I could do it, but it might take me all day. And when you can't slow down and take your time driving from point A to point B, it's natural that it's hard to wait for superchargers.
But, believe me, they will come. In the mean time, do what I did. Go anyway. Get on the phone, find the motels with 14=50s. Go to Plugshare and find where the RV parks are, where the Destination 80 amps are, the private homes, even, that are willing to share. Make it an adventure. And have a good time.
It is about 325 miles from St. L. to Nashville, and there are a couple RV parks in Paducah. Doesn't look like much of a problem if you're really wanting to go. That's an easy day with a few hours top up. Be Brave! If your range buffer starts to drop, slow down, and enjoy the scenery.
And if you ever make it to Napa Valley, be assured you will be Welcome! (I lived 20 years in MO)
