After coming from the railroad industry previously, I can tell you its coming one day. Remember the bad accident in california a few years ago that killed all those passengers. The operator was texting and ran a red signal. Next was federal law, no text and phone calls and no surfing the web anywhere in the cab of the locomotive. First incident killing passengers on a vessel because the capt was texting and ran into something will be the reason to end cells in the pilothouse.
