The Times Square rampage that left a young tourist dead and 22 other people injured earlier this month is spurring calls to further restrict cars from the Crossroads of the World.
Broadway became a pedestrian-only zone at Times Square eight years ago.
Now, some city officials and traffic experts say the car ban should be expanded to include the north-south artery of Seventh Avenue.
There are new concrete blocks and barricades throughout Times Square since the accident.
Richard Rojas, who was indicted by a grand jury last week, told police after his arrest that he had been smoking marijuana laced with the hallucinogenic drug PCP, according to a criminal complaint. He said he wanted to "kill them all" and police should have shot him to stop him, prosecutors said.
Rojas made a U-turn on Seventh Avenue at 42nd Street and started speeding down the sidewalk for about 3-and-a-half blocks, mowing down pedestrians before crashing into a traffic pole.
He is charged murder and attempted murder and is being held pending his July 13 arraignment. An attorney for Rojas did not immediately return a call seeking comment.
He also had two previous drunken driving cases.
