And yet you still don't see headlights on large ships.
No. But you do see greatly improved radar systems, sonar systems and
communication sytems that reduce the risks of these types of accidents from
recurring on a regular basis. The problem seems to be that
technology can't compensate for "stupid" as evidenced by the cruise
ship running aground and sinking while the captain was trying to impress someone
on shore or do a favor for a crewmember.
