Got some heavy snow over the weekend in the Chicagoland area, and I remembered I still had footage of this wild incident. I'm lucky I was able to maneuver and both of us got off free. Immediately exited my car, asked if they were okay, "yeah", and then got back in and drove off to work.
Since then I only take the main roads to work during winter and at night.

Edit: Forgot to mention it was a rather icy morning so that's why they likely lost control.
