The day that YouTube user Michael B bought a Nest camera and trained it on a Seattle highway exit notorious for its spectacular crashes was a good day indeed. The Union Street exit on the city’s I5 highway features a tight curve and a dramatic speed limit drop to a mere 20 mph, and plenty of drivers who either don’t know how to drive or who were simply not paying attention have taken this exit at such a rapid clip that they’ve gone careening into the subsequent intersection in showers of sparks. Today, you’ve earned our permission to pat yourself on the back for being a competent driver as you watch one car after another careen into hell.
