I don’t think it’s wrong, or dangerous. Why am I using my phone while driving? Because I can. Simple answer. It’s my car, my phone and I’ll do what I want, when I want.
I am an important person, better driver than you blokes, so get out of my way! I have meetings to attend, business to take care of, important things that can’t wait; don’t have time to pull over!
Glancing back at the road, seeing a streak of red he ignores, looks back to his phone. He probably didn’t feel the impact when he hit the fire truck.
