So there's now a commercial for the Chevy Volt concept car — which is kind of weird because they're not actually selling a Volt yet, but whatever. In the commercial you've got a line of kids with the sides of their faces planted on the long hard slab of metal that's the hood of the Chevy Volt. It's then that we find out the Volt hums. We're not sure why it hums, especially because we didn't know it even had batteries for an e-flexible engine to feed, but again, whatever. The thing that's disconcerting to us is the fact that Chevy lets an adult male speak to children about humming of any sort. That's just weird.
