London (CNN)There's one question gripping the UK today and for once, it's not about Brexit.
Why is Prince Philip still driving at the age of 97, especially when he has access to a fleet of royal chauffeurs?
Remarkably, the Duke of Edinburgh managed to walk away from the crash unscathed. The prince was "obviously shaken," an eyewitness told the BBC, but he was able to stand and showed concern for the occupants of the other car. The female driver of the other vehicle and her passenger suffered minor injuries, and there was also a baby in that car who wasn't hurt.
Prince Philip once surprised US President Barack Obama and first lady Michelle Obama by picking them up from their helicopter in Windsor in April 2016.
It's unlike Philip to obsess about media coverage of his life but if he does tune in, he will probably feel a mixture of bafflement and despair about the focus on him after this crash.

The Duke of Edinburgh is also famously independent and has been caught on several occasions getting frustrated by the strictures of his public role, asking photographers to "get on with it" and ignoring the instructions of aides.
The quid pro quo for being a member of one of the world's most famous families are the many trappings that come with it -- from historic castles to all-expenses paid hospitality and a fleet of luxury cars, complete with chauffeurs. So why doesn't he use these drivers?

Well, imagine being locked away behind palace walls, unable ever to take a walk outside the grounds, even for a cup of tea without a stifling security detail. The only sense of freedom you can enjoy is grabbing the car keys and hitting the open road. In that case, it's the security teams that are confined -- to the follow-up car.
That's why Prince Philip insists on driving even when he doesn't have to. It's why he famously picked up US President Barack Obama from his helicopter at Windsor Castle in 2016, to the astonishment of the Secret Service. It's why the Queen once reportedly drove the former King of Saud
