Selfies have made our smartphones indispensable. So will we all move on to dashcams? A Dover policeman’s dashcam video of his lip-synced rendition of Taylor Swift’s “Shake It Off” song has gone viral, and that could spur a new way to entertain ourselves and others while we’re in our cars.

The Delaware policeman’s video, released by the department as part of its “DashCam Confessionals” web series, has been viewed nearly 9 million times after just a couple of days. Driving his squad car, the cop does a good job lip-syncing the song, bobbing his head and stopping when he passes people who see him.

There’s already a bunch of copycat videos. If it keeps going, the makers of dashcams are going to be quite happy. Dashcams have been catching on in places like Russia, where safety on the road is a big concern. If people got carjacked or were involved in an accident, they wanted evidence available in the form of a video. That resulted in a lot of car crash videos that also went viral around the world. Little did we know that pointing the dashcam the other way, at the driver, could be an even bigger application.

Taylor Swift responded with her own admiration for the video.
