If we're loosening the parameters to scripted 'unscripted' shows, I gotta put a word in for BBC's Top Gear. Pure gearhead porn with a healthy sense of humor. Taking the most beautiful cars on earth to the ends of the earth in it's diverse beauty, always returning to the Top Gear track and 'Tame Raycing Drivuh' The Stig for comfort and familiarity, awesome cinematography, well-defined personalities. It really is the gold standard.
If you become a technician, you just whup 'em on pure technique. /W.Shields
