Terrorists plan for maximum casualties, not middle of the night when bridge traffic is at its lowest.

“There’s also economic, and psychological terrorism. Doesn’t always have to be maximum immediate loss of life for them to create problems in a society.”
Perhaps, but when there is opportunity to achieve economic, psychological, and human loss in one terrorist event, then that’s what they will try to do. (9/11 did not happen overnight when the buildings were near empty, but during the morning rush our when the buildings and adjoining public spaces were near maximum capacity.)
