I had the pleasure of Living in Southern California for about 13 years back in the late eighties and nineties. During my many hours of commuting I saw people doing the stupidest things. More than one woman putting on makeup while driving, one was actually putting on eyeliner! A bump or sudden brake and the thing would of been in her eye! Not to pick on the ladies, but I actually saw one driving down the road with a portable TV on the dash and she was watching a soap opera!
Allot of my "younger" relations are just absorbed with texting on their phones, it's as though they can't go two minutes without getting some sort of contact fix with the outside world. Most of it is just idiotic banter, nothing of serious consequence, but they just can delay a response because it not "buck" (cool) to do so.
I sure do hope that video has an effect on the teens of the UK. Sorry to say though, I don't think it would do much good here in the states. Shock and Awe has been overworked here and any concern for self-responsibility seems to be lost on the young at this point.
