"Drive" continues an excellent stretch of episodes forming the canvas for season six and is one of the better stand-alone representatives of its particular year. As its title would imply it is a very driving episode, with tension escalating from the news-camera teaser all the way to the tragic final act. Though Mulder and Scully are dispatched to investigate surfeits of suspicious fertilizer, the two agents get caught up in a high-speed road trip when Mulder crosses paths with Patrick Crump (Bryan Cranston), who lived close to a military facility where electromagnetic experiments took place. As a result the frequency in his skull (forgive my scientific unenlightenment) is increasing, and unless Mulder can escort him west and at increasingly higher speeds, his head will explode. Forgive the far-fetched premise and you have one hell of a thrilling episode, penned by the great Vince Gilligan. "Drive" works well as an engaging isolated story, but also in the grander scheme of the overarching plot, where Mulder and Scully have been stripped of their former privileges and are forced to take greater risks on their pursuit of The Truth. This makes the build-up to the episode's denouement all the more exciting. I give it a 9/10.
