Drove them from their hotel, more likely. Do you need bodyguards for something like that?
I guess it depends how high their profile is.
The British royals are always accompanied by their bodyguards. I wonder what the other RFs do?
Just because they drove themselves doesn't mean that a bodyguard wasn't present.
You see often with the Brits for example that the bodyguard is in the passenger seat or sometimes follows in another car.
Depends on the occasion how they can "stretch" the distance between RPOs and the family members.
The trained RPO always drives for engagements, as it's safer. Other than that an RPO isn't necessarily behind the wheel.
