Sir, I very humbly disagree with this. I might not be the most knowledgeable person on the issue, but I am sure that if I was driving in 3rd or 4th gear down the hill in snow on some of those slopes I would've surely ended up in a deep ditch because of the high speed of the car in those gears. I mean, I would have had to control the car with brakes and the vehicle would have skidded badly, allowing me little time to control it. Once again, I don't claim to be an expert, so expert opinions are welcome.
