Hey dude, it's California, what do you expect? The largest collection of stupid people of Earth live there. When the work day stops to watch a car chase being covered by 6-7 media choppers from every TV station in SoCo, you know people have some serious freakin' problems. The sun-stroke afflicted twitching ganglia who inhabit California are probably hoping that they will see some dead body or a shoot out with police. The same people who actively wish to see "breaking news," like a shooting or a dead dude are the major voting block in California; kind of scary ain't it?
Of course, there are gawkers everywhere. NOVA is also a haunt for the morbidly curious liberal who has such a dissatisfying life that he gets his jollies watching tragedies unfold. Move to a rural area and you likely won't encounter chickenhead rubberneckers as often.
