The veteran revealed that his father, who was in a wheelchair still insists on driving.
"So does my father. I'm always worried," Charles said to him.
Of course, Charles’ concerns did not dissuade his father from getting behind the wheel again.
Miraculously no one was seriously injured in the crash that saw Philip’s Land Rover overturn in the collision near the Queen’s Sandringham Estate in Norfolk.
Philip and a passenger believed to be his protection officer were unharmed, but the two women in the other vehicle suffered minor injuries.
They have both since been discharged from the hospital and Philip is believed to be spending the night at Sandringham.
Speaking after details of the crash emerged, Edmund King, president of AA - a UK-based motoring association, said: “We wish the Duke of Edinburgh well. Many commentators use high profile car crashes involving elderly drivers as a reason to call for bans or restrictions on older drivers.
“If driving restrictions based on age and safety were introduced we would be more likely to restrict young drivers rather than older drivers.
“Young, predominantly male, drivers are much more likely to crash within 6 months of passing their test than older drivers within 6 months of hanging up their keys.
“Older drivers often self restrict their driving by not driving at night and only driving on familiar roads.
“The decision to hang up your keys is a tough one but should be based on personal advice from your GP and family rather than being based on some arbitrary age. We all age differently and the car is an essential lifeline for many elderly people.”
