CEE Transportation Engineering Professor Mike Cassidy discusses drivers' last-minute merge and how the move endangers drivers and worsens traffic jams.
He has studied the phenomenon on Bay Area highways by carefully measuring freeway traffic with sensors and cameras.
"Of all the maneuvers, it's probably the most disruptive to traffic," Cassidy said. "If the police were to say, 'We're going to crack down on one type of maneuver,' that would be the one. It would likely have the most significant effect on traffic."
