Here is a video of a 2006 Ferrari which was burning on the side of a highway. For the first part of the video cars just keep driving by ignoring the burning Ferrari until finally someone stops the traffic. Near the beginning of the video it looks like the gas tank explodes because there is a huge fireball plume before the fire dies back down. It seems like the driver of the Ferrari is standing a ways back down the road calling emergency services on his cell phone. Guess they don't make them like they use to huh?
