I don't know what to think about Elon Musk anymore. I mean the SpaceX stuff is awesome, and the Tesla car has been pretty cool. But now we have the Tesla pickup truck, unveiled on Thursday. (Simone Giertz did it first!) The Tesla Cybertruck looks odd—one person likened it to a futuristic doorstop—but that's fine with me. My problem is with the unveiling itself.

In case you missed it, Musk wanted to demonstrate the truck’s ruggedness. They start off by hitting a normal truck door with a sledgehammer. Yes, it makes a dent. What about the Tesla truck? Bam! Not a scratch. It has a thicker steel exterior that makes it impervious to people with sledgehammers.
