I live in Vancouver but work in Kelowna a few days a week. This winter has been intense on the Coquihalla and i'm wondering if the Model X is up to the task. 1. At -12 how will the vehicle perform in respect to range? It's about a 370K trip and I want to do it on a single charge. 2. With up to a foot of snow, slush, ice - can the X handle these conditions? 3. The flying rocks have destroyed my windshield. Each trip I get another chip or crack - How durable is the model X window? Any advice is appreciated, I'd really like to get into one of these, but need some assurance it's up to the insanity of my weekly commute. Cheers.
