I didn't know things like that were so common since I haven't taken the electric plunge. Does the supercharging diminish battery lifetime? Is there a danger of rapid charging (electric cars have somewhat of a bad rep regarding fires)? How much is a supercharge "fillup"?
I see most of the questions have been answered below, but it may or may not makes sense depending on where you live and driving patterns to take the plunge. I held off a long time because there really wasn’t a car that had the range (at least for what I was willing to spend) for my travels. I needed realistically about a 150 mile range to be safe for it to be even a “local car. Others around Atlanta did just fine with the Leaf (about 110 miles at the time) as they were just buzzing around town and there are plugins all over the place. Somewhere like Starkville, (for now) you would realistically be pretty range limited unless your place of business etc had a normal 110v plug (or charger) with any of the short range EVs.
The Telsa gives you the city commute with no worry and cross country range. If I were to go way off the beaten path (interstate system) I would be somewhat ranged limited without an overnight stop as most of the non supercharger type station will get you 20-40 miles per hour as opposed to 400 MPH with the SC. Although if you stop for dinner, the mall etc, you can plug in to top off, it isn’t like you are gonna sit there for 3 hours fueling up on a long road trip with those types of chargers.
There are are all kinds of arguments of fuel cost savings, environment, politics etc that people use to justify to purchase, or to argue against an EV. For me, I will most likely never save a dime over an ICE car (compared to the Model 3 price) but I absolutely LOVE driving the car, the technology, and plugging in for cheap at home. The fact that I can can turn on the AC from my phone (from anywhere) after it has been sitting in a parking lot all day, might be the best part

It is like getting a new car, smart phone and IPad all in the same day.
If anybody has seen the air quality in Atlanta in the summer especially, i certainly like the fact that I am not contributing to that problem as well.
Whether you are a fan of Tesla or not, just about every manufacturer has a 200 plus mike range car coming next year, or in development and the prices are coming down fast as the infrastructure to “fuel” them is growing by leaps and bounds.
