Chicage actually is one of the top markets for the Model S. You probably will see a lot more Model S AWD in the winter. It missed last winter but will be very popular in the snow country due to its superior capability in the snow.
You're analysis makes a lot of sense. Funny that how people always say Tesla don't have a future because I don't see how they could do it. That's why there is only one Tesla and it's not started by anyone of you.
Did you see how many BMW 3 series are there and how hot the Porsche Mecan is selling? The new Model 3 sedan and crossover will eat them all for lunch. All of them will become low performance sedan/cuv when model 3 comes out.
