Your claim about the storm and EVs causing a problem is BS. We were driving in Virginia when that storm hit. The bad weather was forecast. On our second day of the trip back from TV to NJ, we departed early in the morning when the storm hit. The temperature when we started was about 38F. The temperature dropped 1degree Fahrenheit per 10 Interstate miles driven. I was not having control problems. I was very familiar with driving in worse conditions. That said, changing lanes was tricky because the snow was accumulating between lanes, which will cause a skid that needs to be managed carefully. I chose to exit and find a place to stay because the traffic was heavy and it was clear that too many other drivers were unlikely to be able to handle the conditions. The roads had not been brined or salted, which would have been normal in more northern states. Lack of road treatment was the most important cause. Had they been properly treated and plows had been ready and available, that road probably would have stayed open and moving.
We pulled into a hotel mid-morning and waited for checkouts and room cleanings. By the end of the day, the interstate had turned into a 50 mile parking lot in both directions. Cars were actually stopped dead and remained out overnight. Naturally, clearing the roads was extremely problematic well into the next afternoon!
The next morning we left at almost noon. All of the roads, even off the highways were a mess. Many were blocked. In my lifetime, I had not seen so many vehicles that had departed the road, in many cases far off the road. What should have been a 4 hour drive turned into nearly 12 hours. Most of that time was spent on the first 60 to 120 miles. We did not get onto a major highway until we got to Maryland.
As to the claim about heat. It takes the same amount of energy to heat a car, regardless of its power plant. That is basic physics.
