I disabled my chime in my car... then I realized it was connected to the same power connector that powers the sensor-thing to lock my seatbelts when I brake hard.

Stupid me. Needless to say I re-attatched it, 'cause without it my seatbelt is no better than a lap belt...
Bing.... bing.... bing.... bing....
I agree with Zeno. Back in the good 'ol days this wasn't a problem, but more cars + faster cars + traffic + road rage = more chances for accidents and death...
But I do think it should be up to the person themeselves whether to buckle up or not, except children. Perhaps everyone under the age of 16 or so must be buckled up... not responsible enough yet or some crap like that.
