Actually, beginning in 2008, it will be illegal for drivers in California to drive while talking on a cellphone. Bluetooths and other wireless devices are allowed, but cellphones will be banned while driving period. The law was supposed to go into effect earlier this year, but it got pushed back. Personally, I wouldn't want to waste my time pulling people over for that, unless I saw an imminent threat to others on the street. The CHP can handle that.
