I just have one HUGE problem about this law... I now have no way of knowing if a driver with a headset is actually talking on their cell phone. And let us admit it... talking on the cell phone while driving, with or without a headset, takes away the driver's attention.

The only way I could determine if a driver with a cell phone would be a danger to me was to see if they have their cell phone held up to their ear.

What CA government should have done was banning cell phones from all Class C drivers while driving. So when any one of them is breaking the law by having their cell phone held up to their ear, everyone else can see that and distance themselves from that driver.
