At first I thought it was a good idea, as just having people know the law exists would discourage at least some texting while driving.
Problem is that they don't want to post it. Which means they are just looking for a stupid motorist tax. Sure you shouldn't text while driving, and if you get pulled over for it, you deserve the ticket... However, you should at least know that it's illegal so you can keep from doing it.
As for already being able to use reckless driving, many people would be able to get out of that ticket. Its just another offense to add on to make it stick
