Words to Drive By

 My sole passenger is six years old and strapped into his child car seat in the rear seat of my car.  As I start to back out of my driveway onto the highway, I see him in my rearview mirror craning his neck to check the traffic and hear him say in a confident tone, as if he's done so many times before, "Okay, you're good."  I catch myself, look for myself:  he's right, nothing is coming.  But you can't do that, can you, rely on a six-year-old's assessment of traffic flow?
