That's what is terrific about the Model S. One does not have to be a 'car person' to really appreciate that vehicle. I would say that if you are already considering it, go ahead and get the S. You will most certainly not regret it.
I'm not a car person and I appreciate why people like high-end cars. I had a lot of fun a couple years back tooling around BMW's track inSouth Carolina. However, because I'm not a car person, I also can't see paying $100K for a car given other ways I could spend the money.
You generally don't need to be a car person to appreciate a luxury vehicle. Not sure how the model S is different from any other luxury vehicle, who's target audience is not car people, but just people with higher disposable income for cars.
