When a six-ton elephant suddenly lumbered over to the Volkswagen Golf in a South African safari park, Rico Beltrame and his sister Angela feared it was going to reduce the vehicle to scrap metal - with them inside.
However, the giant tusker turned out to be more curious than crazed. Coming to a halt alongside the car, it plonked its massive trunk firmly across the roof, slightly denting it.

Trunk route: The African elephant dwarfs the tourists' car in Hluhluwe game park
A park ranger shouted over to Mr Beltrame to switch off his engine - which he did with a trembling hand. Then the 12ft elephant just stood there, gazing down at the rented Golf as Mr Beltrame and his sister stared back, frozen with fear.
For six minutes the standoff continued, with the brother and sister expecting at any second that the roof would come crashing down on them.
But, finally, the elephant removed its trunk and calmly walked off into the undergrowth at the Hluhluwe game park in KwaZulu Natal.
"We saw a group of elephants and started taking photos," said 27-year-old Mr Beltrame, from Switzerland. "Then we saw the elephant head our way. We got very scared when he stood by us and put his trunk on the roof.
"We waited, sitting without moving, waiting, before the elephant continued walking. It was an unbelievable experience."
The reserve is also home to rhinos, lions, leopards, crocodiles and cheetah – any of which might have been more interested in a snack than a peek.
