Last week, I drove from the SF Bay Area to Lake Tahoe. Above 5000 feet, it was snowing (heavy flurries), snow on the surface, temperature 29-31F, on a two lane highway (US50). We stopped for 2 hours while an avalanche was cleared, and then resumed travel in the dark. Soon, the road was barely visible through our iced windshield, with occasional white-outs from blown snow. I was reluctant to scrape the windshield due to concerns that I would be hit by a sliding vehicle, but when I was able to scrape it, it quickly frosted again. While the traction was superb, there are serious Model S winter driving shortcomings: The front windshield defroster is grossly underpowered, inadequate to keep ice from forming, and it was barely freezing There are no heaters at the base of the windshield to keep the wiper blades from freezing There are no heaters to keep the windshield spray nozzles free of ice There is no wiper blade or spray nozzle to clear the rear windshield There is no spray nozzle to clear the rear camera Because I was unclear as to the meaning of the blue vs orange indicator on the front windshield defroster, I discovered there is no Tesla User Manual when there is no cell service Without internet access, when I attempted to tune into an AM station for road conditions, I discovered that there is no AM radio I drove slowly, peering through 2 to 3 inch gaps in the frozen windshield. When we finally arrived at Lake Tahoe, I spoke with a Model X driver at a super charger who reported a similar issues. It was an absolutely terrifying experience which we survived. With a couple of exceptions, I would expect these features on any modern automobile, and certainly all of them on a car costing $100,000.
