the cell phone law in Mass. ... and how nothing has changed...

In September 2010, a new was passed regarding cell phones and driving: It was PROHIBITED.
That included texting and/or talking.
All of my classmates and co workers at the time were completely angry at this and it's obvious why: we ALL texted or answered the phone while driving.
From time to time some horrific accident is reported in the paper or news show that was provoked due to one of the drivers (or both) using their cellphones.
So the law was passed. Now what?
Does this mean that people stopped using their cell phones completely while they're on the wheel? NO.
Some of people are incredible multitaskers. They'll shuffle music on their ipods, they'll reply a text message or pick up a phone call, all during the drive. My sister and my best friend are like this. Others are a litle slower (like me) and when we're driving it's incredibly hard to move our hands away from the wheel (I'm so bad that even to turn the volume of the music up on the little button on my wheel I have to stop or not do it at all).
So does this makes me a follower of the law? NO. If I happen to be at a stop sign I will reply a text message or make a very quick phone call.
I honestly haven't seen anyone that I know getting a ticket or being punished for this.
And some people are really obvious too. Like this lady on the highway who cuts me off and then drives in the middle of the two lanes. Once I managed to pass her she was on what it appeared to be a heated conversation on the phone. She never got fined either.
Anyway, so what is the point of this law if is not being enforced?
