The Scorpion and the Frog tells the story of a scorpion who wants to cross a body of water. The scorpion cannot swim and approaches a frog to seek passage across the river. The frog is hesitant, well aware that the scorpion is a dangerous creature who is likely going to sting the him during the journey. The scorpion reassures the frog, explaining that if he stung the frog, they would both drown. The frog sees the logic in the scorpion's argument and agrees to carry the scorpion on his back across the water. However, half way across the river, the scorpion stings the frog. When the frog asks, "Why did you sting me?", the scorpion replies "Because it is my nature", after which both creatures drown.
The story of the scorpion and the frog is one about understanding the inherent nature of some people. A scorpion is and always will be a killer. A criminal is and always will be a criminal.
The thematic device of the scorpion boards for the movie Drive is intended to illustrate the concept of the frog and the scorpion fable while indicating that the nature of the Driver character played by Ryan Gosling is one of a killer who cannot help himself. By placing the scene under water, the narrative depicts the way in which, due to his nature, Gosling's character cannot help but drag his counterparts down with him on his spree of self-destruction and murder.
