Okay, story time. So, my brother was a law student in SF. He had a class on maritime law. They took at field trip to the Mare Island DHS office (I think) to learn more about the implementation of all the law they were learning.
So, they learned, in response to the Cosco Busan oil spill (I think), DHS decided to put in a warning system that would track all the boats in the Bay and then alert the DHS office if any of them were going to crash into Frank's Crab Shack again. Look at the trajectories, guess the time, send out an alert to the whole office. Years are spent on this system, millions of dollars, lots of studies, yadda yadda yadda.
The warning system they decided on, because this is the government and they know about lawyers, is that the whole office is going to have red flashing lights and a very loud voice come over the intra-office speakers saying 'CRASH IMMINENT". And then it'll just blare that notice until the S/W decides that the crash ain't happening anymore.
So, my brother there and they are taking the tour and the alarm goes off and ... no one does a damn thing. And he's thinking that this is really strange. And the tour guide they have looks at the group of law students and explains the above. And then the tour guide goes and says ' but they forgot about the fucking Rocket Boat'
So, in the Bay at that time, there was the Rocket Boat tour. You get on at Pier 39, you go on a tour at really high speeds, bumping your clam chowder out along the way. And to scare the tourists at the end, the pilot heads straight for Pier 39 and then turns away at just the last second. Tourists are scared, but happy, a bit wet. Everyone has a good time.
Except for the DHS office and their automated crash system. Every. Single. Time that the Rocket Boat decided to scare the tourists, the alarm system would sound.
So, since this is the government and you certainly cannot turn this millions of dollars system off now, nor can you really really be certain that the Rocket boat driver didn't actually just pass out from all the beer-only lunch he just had, the workers at the DHS office just had to endure the booming alarms and lights. Multiple times a day, nearly every day, all year long.
So, I think an automated system is a great idea. But, for the sake of all the DHS drones: Please, make the system smart enough to deal with the Rocket Boat.
