It wouldn't surprise me. Wealthy guy who lived in New York City his whole life, where he was probably driven around everywhere he went as an adult and wouldn't have had a reason to learn as a teen. Other than golf carts or something, he might never have had a reason to drive.
Probably lots of politicians fall into that category, as well. When's the last time Joe Biden, Bill Clinton, Hillary Clinton or George W. Bush got behind the wheel -- not for an appearance or publicity stunt, but on an actual public road in traffic to take a road trip or run to the store?
