Congratulations, we love our model S -- and we love the "never go to the gas station" lifestyle.
But I think you are playing a semantic game when you define "range anxiety" as "I don't go to the gas station when the dial is on E". That's on you.
Range anxiety is a real deal and evening traveling in an S100D, I'm here to tell you that it's more limiting cross country than an ICE. For me the moment range anxiety hits is when I'm going from the last super charger to a final destination that is some distance away and where there's nothing but 120v charging.
It's a real thing, and a thing separate from your "I won't run out of gas because I can't be bothered to fill on E when around town" lifestyle.
