neckout
n.— «Bottleneck roads are prime candidates for road rage. I have no idea who designed roads that lose lanes, but they had better go back to the drawing board. Traffic neckouts, as they’re called, will not improve our road problems; they will only make them worse.» —“Neckouts + lane arrows = rage” by Ed Boger in Bradenton Herald-Tribune (Sarasota, Florida) Jan. 15, 2007.
