At one time Bunting was a legitimate (read: objective) host of computer shows on The Discovery Channel and PBS. He used his name to morph into a less than objective infomercial host.
The United series is an infomercial of the worst kind, one that can not be easily identified as one. Jet'Dillo's comment is right on. He's hyping technology that is less than state of the art to an unassuming audience of "self loading freight".
