As reported by the Riverfront Times, the blue Huracan was actually one of two Lamborghinis, the other being an orange Gallardo, that had stopped to refuel. This video shows the exact moment when the minivan driver pulls away and the fuel hose separates from the pump. Careful if you're watching this at work, or have kiddies present, because some of the language is, well, also incendiary.
Then again, if you're in the middle of seeing gallons of fuel being sprayed directly onto a supercar's hot-running V10 engine, we doubt you'd wax poetic about the experience. And due credit to the Riverfront Times for its headline proclaiming "Incredible Dumbass Turns Lamborghini into Fireball at St. Louis Gas Station." It might not earn a Pulitzer, but kudos for nailing the story in one line, folks.
Apparently and, somewhat amazingly, no one was reported hurt in the ensuing fire. The Lamborghini is definitely a total writeoff, but amazingly, the accompanying red Performante was just covered in ash. And according to this same Facebook post, the minivan driver was quickly found and admitted to being the culprit.
Update: A previous version of this post incorrectly identified the blue Lamborghini Huracan as a Gallardo. The text has been corrected. Additional photos and video have also been embedded.
