Vice President Joe Biden is many things, but the self-confessed gearhead had a confession of his own to make: he underestimated Tesla, and lost $10 in the process.

After a private meeting with Pope Francis at the White House, Biden spoke with Cardinal Pietro Parolin, the Vatican Secretary of State, and his "Uncle Joe" persona came out in full swing (transcript by poolreports):

BIDEN: What an honor to see you again.

(SHAKE)

BIDEN: I don't know whether you know, your photograph is hanging in my office.

PAROLIN: Oh yeah?

BIDEN; Yes, from our meeting.

PAROLIN: You have already met with the Holy Father.

BIDEN: I have met with the Holy Father. And I've met with these guys, too.

(GESTURES TO POOL THEN GRIPS YOUR POOLER)

BIDEN: I had to pay this man $10. He's from the New York Times. We had a bet: which is the faster car, the newer Cadillac or the new Musk car. Which?

POOLER: Tesla.

BIDEN: The Tesla. I bet the Cadillac.

POOLER: He went for the old technology. I went for the new.

PAROLIN: Oh yes?

BIDEN: The Tesla's two tenths of a second faster. But I lost. I paid my $10. (LOUDER TO ENTIRE POOL, ROOM AND PERHAPS CITY) I want the record to show, I paid my $10.

MEMOLI (CATHOLIC REPRESENTATIVE IN POOL): Does that count as a confession, sir?

BIDEN: I'm seeking absolution!

Biden, long a car lover, owns a 1967 Chevy Corvette (a fine car, even if it is a 50-year-old internal combustion machine) that the Secret Service won't allow him to drive anymore. But the two cars in question in this bet — presumably the Tesla Model S P90D and the Cadillac CTS-V — are something else entirely.

For comparison's sake, the Model S hits 60mph from a dead stop in 3.1 seconds — or 2.8 seconds if equipped with the Ludicrous Speed Upgrade — on its way to a 155mph top speed. The CTS-V, on the other hand, lumbers up to 60mph in 3.7 seconds (who are we kidding, that's still bloody fast), but given enough time will blast past the Tesla with a top speed of 200mph. Both cars are stupid expensive and impractically fast, but goddamn are they fun.

So much fun, here the two are drag racing:

But, it's okay, Mr. Vice President, you're far from the first person to underestimate Tesla, and you'll be far from the last, even once the Model 3 begins to arrive in driveways across the nation.
