Could you possibly clarify who you're referring to as the "billionaire son in F1"? As Formula 1, or F1, involves numerous individuals from diverse backgrounds, including those who come from wealthy families, it's difficult to pinpoint a specific individual without further context.
However, if we're looking at the broader context of Formula 1 and wealthy families, it's not uncommon for drivers or team owners to have significant financial backing from their families. Some drivers or team owners may indeed be the children of billionaires, but without specific names or details, it's challenging to provide a definitive answer.
Perhaps you could provide some additional information, such as the name of the driver or team owner, or a more specific description of the individual you're inquiring about? This would help me provide a more accurate and informative response.
