I disagree vehemently. That is one of the reasons why it's illegal in Denmark to use a hand held phone while driving even when stopped at a traffic light.
Would you mind explaining the logic?
(genuinely curious. I've heard of laws like that. But I thought it was the same logic behind not allowing passengers to drink i.e. The banned activity is not really harmful, but the law takes away an excuse from the driver doing the harmful activity)
I don't mind at all
The way I've heard it explained is two-fold. First of all, by making it illegal to use a phone at all
while driving makes the deniability smaller for those who'd break the law regardless. They can't go "Oh, I was only using it when stopping at a read light", since that's illegal too. In other words it makes it easier on the traffic police who already now have to ward off insane excuses
(Best one I've heard, "I wasn't talking on the phone! I was just letting the caller know that I was driving so I couldn't talk." ... and just how did you do that without talking on the phone in the first place? To make it even better, there was a passenger in the car who could have delivered that message!).
Secondly it's the external distraction factor. Elisabunny might say that daydreaming or looking at the scenery is equally distracting, but apparently the police doesn't agree. At least if you're daydreaming you're still looking out of the car. You're not as likely to miss that a red light has turned green.
In Denmark talking on the cellphone while driving is a 1500DKK fine (~US$300). Granted, Kindles and other ereaders aren't mentioned specifically, so you might get off on a technicality - but I wouldn't count on it.
(As an aside, it's actually also illegal to talk on the cell phone while biking - that's a 1000DK fine (~US$200). )
