Riding on Saw Blades on a Frozen Lake

You can gain a lot of traction by replacing your vehicle's wheel with saw blades, but at what cost? Sawing through the ice? Lauri and Anni Vuohensilta put heavy-duty circular saw blades on their Subaru and took it out on a frozen lake. How long can they drive without cutting themselves a drowning hole? From the looks of it, not very long. Contains NSFW language. "Yeah, I think we have, for a break, we have to think about things, and then we start to drive." (via Laughing Squid)
