I can see car insurance companies using this to lower rates as stated in the article. Though it could also be something forced on people by their insurance companies once they have been involved in a texting related accident. It seems wrong that people can't have at least the smallest amount of common sense when driving. A vehicle is a deadly machine in the hands of an inattentive driver, deadlier still, in the hands of a driver that thinks they are the exception to the rule.
Even with the discounts from insurance companies, disabling cellular data to your phone while driving has a lot of other poor implications. Did the article say anything about internet radio? I listen to spotify almost exclusively when I drive and it wouldn't really be worth an insurance discount for me to switch back to over the air radio again. It is an interesting idea I just don't see it catching on.
