That could have ended badly
People are idiots.
When I was young and dumb, I used to take my car places like that, but I was at least prepared. I had Carharts, boots, gloves, extra clothes, blankets, food, tire chains, recovery gear, a shovel, pick, and a High Lift.
I got stuck, but always got myself out and home.
I really started seeing stupid when I moved to California. Just like the guy above, summer clothes, street tires, zero supplies of any kind, and stuck in a snowbank as far up the mountain as they could make it.
