Street rides are like a chess game, wherein different threats can come from any quarter, at anytime. Let’s say you’re a king, perched up high and mighty on your new ADV. Powerful as you are, there’s still risk—risk in the form of the suddenly swerving lane-change guy heading for a freeway exit; like a bishop, he can angle across the entire chess board in one shot. The rook is a dimwitted blunderbuss tailgating and crowding everything out of its path, you included. And the exalted knight? An erratic psychopath ready to turn left in front of you.
