<<PEOPLE! When the bloody hills are slippery, keep your wheels moving, no matter if the back end of your vehicle is waving in the wind. Steer like you were taught in driving school. I then took the hill at 35mph and it was a breeze.>>
Sorry, I'm not impressed with this line of reasoning.
You need more traction, such as that provided by chains or studded snow tires. People ahead of you are entitled to slow down or stop if they need to do so, and you need to be equipped to deal with that reality.
Similarly, driving 35 MPH on a steep, icy hill sounds like driving at excessive speed to me. You were driving too fast in order to make up for not having adequate traction to drive at a slower and safer speed.
