I just took 2400 mile round trip in my Model X. Couple of times, the battery percentage went in red zone before reaching the next supercharger. I was bit nervous, but never had any problem. The lowest percentage, I had was 5% and 14 miles. I am just curious about going to less than 10 miles range. Have anyone experience lower than 10 miles? What is the lowest? Does the vehicle go beyond 0%? If so, how long? Knowing this will help me and others, calming the nerves, if it happens again. Thanks.
