You Are On The Fastest Available Route is a great dashcam horror short
by Rob Beschizza from on (#3ETNS)
Local58 is a YouTube channel for a news affiliate that does not, thankfully, exist. Written and edited by Kris Straub, each video depicts increasingly alarming emergency broadcast interruptions and test cards, all implying invasion, revolution or government mindfuckery. (NOTE: "Contingency" instructs the viewer to kill themselves and others).
My favorite, though, is You Are On The Fastest Available Route (embedded above), three minutes of creepy dashcam perfection based on an idea by Mikey Neumann.
