I have yet to see a Tesla with out of state plates. On my last trip to the Olympic Peninsula of WA, I only saw 1 Tesla on the highway and it was on I-90 as it crosses the Columbia River/Wanapum Lake. The US is a damn big place, and if I spend a lot on a vehicle, I want to be able to enjoy it on long trips. There was a Tesla Supercharger station in Sequim, WA, but I didn't see a single vehicle using it.
I see about two-three Teslas per week, not counting the one that shows up in the parking lot at work. Much fewer LEAFs and Bolts.

One also has to remember that the Li-Ion batteries in an electric car like a Tesla have a very narrow temperature band at which they have their full rated capacity, around 70 degrees. Electric vehicles have a tough time in winter as the cold temps reduce battery capacity at a time when the occupants in the vehicle and glass surfaces need heat.
ICE vehicles also lose efficiency and have problems starting in the cold. As I understand it, the Teslas thermal management systems can and do somewhat mitigate this.

If you're going somewhere where there is a charging station, it likely isn't located at your intended destination. You have to go out of your way to get to the charger and either have to wait for a quick charge or find transportation between your vehicle and your intended destination.
This is becoming less of an issue as Tesla has continued to roll out their super charger network. You can see a map of the network here:

Gasoline has about 100 times the energy per volume as a Li-Ion battery. It's also abundantly available and your on-board storage (fuel tank) will typically last the life of the vehicle. In the winter, heat is scavenged from the combustion process and doesn't create extra load on the system.
Too bad most internal combustion engines only manage thermal efficiencies in the 20% range, wasting the rest of all of that energy dense fuel as waste heat.
