I have mixed feelings, I really don't like the idea of any of these tests. Years back when cellphones were just becoming popular, I remember them saying they may ticket drivers for using them. At the time I said that they need to stop making new laws for every little thing and should keep their nose out of cell phone user's business. At the time I didn't own a cell phone, didn't get one of those until many years later, and just got a prepaid flip phone for emergency use.
Even before texting was popular, I saw enough fools on the roads and highways yacking on their cell phones and ignoring everything around them. We once were almost run off the highway at 70mph by this woman who swerved into our lane, completely oblivious to the other cars on the highway and had no clue that there was even a near serious accident caused by her. Luckily my husband is a good driver and was able to gain control before we rolled over onto the median, or worse, onto the other side of the highway in oncoming traffic.
As time goes on and I see these careless people texting now, it really angers me. They'll park 1 1/2 car lengths from a red light and have their head down both hands busy tapping those keys. Light changes, they're not going to budge until they add their smiley face and click send.

Weaving over the lines is commonplace anymore, and funny the cops never see these jokers and pull them over.
I never sent a text in my life, and I don't talk on the cell phone while driving. The only one who would call me on the cell is my husband, if he needs to ask or tell me something while I'm out and about. Then he knows if I can pull over somewhere I'll talk for a minute, but many times I'll just call him back asap, when I'm parked or out of the car.
Soooo, I'm to the point where I want to see this madness stop. It's too dangerous because people are obviously too foolish to handle such a convenience. Oprah had a show once on texting drivers (teens) who killed people. This girl was touting that she could drive with her knees while texting and drove better doing it at high speeds. They video taped her and it was troubling for sure.
What happened to the time when people took responsibility for their own actions and had some common sense? Technology is turning some people's brains to mush I think.
