I agree with the last comment. And “Oh WHAAAA!! I had to wear an insulated coat or I would freeze to death.” “I couldn’t see out the window!” Maybe he had brain freeze. He could have used the window scraper inside. A credit card works great for scraping ice and leaves cute little curls on your dash. I agree it’s not comfortable, but he said after a few days(?) he had to put on his coat? This means he’s stopped more than a couple times at places that have EV charging & probably a room to rent for the night. And cellular service or at least a land line. PLUS he had Self Driving capability. He was set. Get the truck fixed and carry on.
