I wasn’t sure where to categorize this, under iOS, Android, Photography? Security?
In Germany, the emergency services have been campaigning against “Gaffer” (rubberneckers) for a couple of years now. Firemen have been seen hosing down people who open their windows to film a crash, although that doesn’t always end well.
Police have taken to pulling rubberneckers out of cars and marching them to the accident and asking them, if that is what they want to see? What would they think, if they were laying there, their bones exposed and people were filming them?
None of this really seems to work. Now, the ambulance services are experimenting with putting QR-Codes on their vehicles, clothing and emergency backpacks, which will trigger smartphones trying to film the scene to pop up a website telling them to stop rubbernecking.
It causes tailbacks, people don’t leave a “Rettungsgasse” (emergency lane) open (the left hand lane has to pull to the crash barrier and the middle/right lane has to pull as far left as possible to leave a lane open for emergency vehicles - the problem is, egotistical p****s use the lane themselves, to get to the front of the queue, and thus stop emergency vehicles from reacher the accident, or they turn their vehicles around and drive the wrong way up the emergency lane to get back to the previous exit and leave the autobahn.
(It is already an offence to film an accident, unless you are accredited press, but the police usually have more critical things to do than hand out hundreds of tickets, such as cone off the accident, save lives, clean up the area and ensure other services can reach the site.)
Sorry, the links are only in German:
The Chip page has a copy of the QR-code, you can scan it to see what happens to people that try and film an incident - it brings up a page telling the phone user that rubbernecking can cost lives (in German).
