Should I call out my friends for using their phones while driving?

There's no question that 'distracted driving' can be deadly - so why are so many of us reluctant to take a stand against it?

A friend drove me to work the other day and, while she was driving, picked up a call on her cellphone. It was a short conversation and after she hung up, she apologized, but the episode left me feeling uncomfortable. Should I have called her out or am I overreacting?

I suspect you don't need me to tell you that your nervousness is well-founded: the statistics on car accidents and phone use are incontrovertible. In 2015, approximately 3,477 people were killed, and 391,000 were injured, in car crashes caused by "distracted driving".
