The idea behind drunk driving laws and their harsh punishments is that when someone drinks he degrades his ability to drive safely. If he drives in this state he has placed himself and others in greater danger because he MAY cause an accident.

I will support this idea when it is uniformly applied to all behaviors that degrade a persons ability to drive which MAY cause an accident. It's a long list but let's start with cell phones. Now that it's been established that the risk of being in an accident while talking on a cell phone is the same as .08 BAC, When a cop sees someone talking on a cell phone while driving he notes the time, pulls the perp over, he askes for the cell phone so he can check the time of the last call. If the driver refuses automatic 6 month license revocation plus he still goes to court where his phone records are checked and compared to the cops arrest record. If guilty, 3 days in jail, 2 days in training, one year with a yellow license plate to allow you to drive to work. And this is on the first offense.

If you think 3 days in jail is a little harsh for talking on your cell phone while driving; and there might be 1 or 2 of you that have done that, then either the punishment for DUI is too high or for Driving While Phoning is too low. It's as simple as that.
