I was looking for that earlier (and hoping not to find it, to back up an assertion that he didn't). Unfortunately, I found an article that claimed to link to a YouTube video of him driving his Rolls in Florida while listening to Taylor Swift, but the video had been deleted.
Other than that, all I've been able to find are pics of his driver's license and him acting like a toddler in those photo-ops with the big rig and the garbage truck.
Doesn't count, because he's not driving and only demonstrating the most rudimentary understanding of how it works, but this was the first thing that came to mind.
