> a spot on a track day at Silverstone

Silverstone is a racetrack and a "track day" is a non-raceday where the public can drive the course. The author's metaphor still doesn't make a damn bit of sense though. I think the author is trying to say that Scorcese didn't deserve an Oscar for the Departed or that he's well past his ability to be an honest contender, but he's not clever enough to stick the landing.

edit: Or maybe auocorrect made a mess of the article and the editor didn't give a shit about this clickbait.
