Bluetooth headset sales booming after legislation changes in CA and WATalking while driving just got a little more expensive on the west coast. Legislation went into effect last month in California and Washington requiring the use a headset of some sort. California's law was passed way back in 2006, yet most would-be good citizens waited until the absolute last minute to comply, with sales of Bluetooth headsets surging to four-times the national average in the months prior according to the NPD Group. Still, 7,182 citations were handed to naughty Californians in July. Up north only 100 were nabbed, as Washingtonian drivers can't be pulled over unless they commit some other violation as well, making headset use there a little more ... optional, so long as you lay off the throttle, Speed Racer.
