I just returned from a ski trip to Mont Tremblant, north of Montreal, Quebec, Canada. I love my Tesla except in cold weather. It is ironic that the rear mirrors on the doors are heated but there is no air vent on the doors to defog the windows so you can't see the mirrors. As the car accumulates dirt, driver assistance features, including cruise control, stop working. Battery range dropped by up to 30%. It is a great car if you stay in the city and keep it clean all the time. But, it is not a car to take you skiing.
