Here is a real-life scenario to consider: Cars and trucks were stopped on I-10 outside Kerrville Texas (in the Texas hill country) in freezing conditions for 17 plus hours in early February after a couple of 18 wheelers jackknifed. There were no wreckers in 100 miles that could handle 18 wheelers, so the sun had to come out and ice had to melt so they could reach the blockage. Even after traffic began to move the next day, it took many hours before the miles of stopped vehicles got to safe open road. At the end of the wait, the emergency personnel were able to bring gasoline to those who ran out trying to keep warm and alive overnight. I was there and lucky. By the grace of God, I was stopped in traffic just shy of the first Kerrville exit and was able to reach it by driving a couple hundred yards on the icy shoulder of a bridge to the exit. Most were not so fortunate and had to tough it out on the highway. After that experience no electric vehicles for me. To my way of thinking, after you run out of juice trying to keep warm there is not one thing emergency services can do for you; gas won't help you. I guess after the traffic has cleared and a wrecker becomes available you can get your vehicle moved to a charging station at considerable expense.
