Called the police on my cell phone while driving down to report this insane Camry.

If there is one reason and one reason only to carry a cell phone, this is it.

"Hello, 911? I'd like to report an insane pickup driving on the other side of the double yellow line, directly into oncoming traffic, heading straight for a blind curve at twice the speed limit or perhaps twice the speed of light, I have no radar detector. Could I have some intervention before we all splay down the mountain?"
