Here's a free tip: If you see a large chunk of metal in the road, you should do whatever you can to avoid hitting it. It could do huge damage to the underside of your car.

Or even worse, it could be attached to some wires and flip you over.

Once again, a Russian dash cam comes to the rescue to bring us this footage of a Ford Focus hitting what appears to be metal and wires that fell off a tram outside of Moscow.

Instead of just running the pieces over and going on his merry way, it ends up teaching the driver a very valuable lesson about road debris: Don't hit it, ever. Just don't do it. It appears he was ok, but the Focus definitely wasn't.
