SALT LAKE CITY - We've heard of driverless cars being tested by Google .
And "How Stuff Works" even explained how they'll operate.
But the driverless car in this video probably doesn't belong to Google and we don't have an explanation for how it works either.
In the footage, you can see the vehicle drive -- in a relatively straight line -- through a snow storm down a highway in Utah.
Watch the video in the player embedded above.
The man who shot this video called the highway patrol for help but because there were so many other accidents, they couldn't get to it. As far as we know, the car hadn't been stopped or found.
