digi-necking
n.— «Rubberneckers attend to the spectacle so avidly that they themselves then get into accidents, slamming into the car in front of them when it brakes to get a better look or dig out a cellphone to take a picture. (This happens often enough for traffic types to have coined a word for it: “digi-necking.”)» —“Tom Vanderbilt’s ‘Traffic’” by Mary Roach International Herald Tribune (Paris, France) Aug. 8, 2008.
