Well, during my holiday in the year 2000 in India I saw a couple of tigers close-up. One when I was inside a small, open jeep and it walked past us at a distance of only 3 metres. And another time was from the back of an elephant. You may think you are at a safe height when you're on the back of an elephant, but you're not. Your legs dangle only a mtre or so above the ground (the lephant wasn't really that big and I'm quite tall so my legs will be closer to the ground). The tiger we approached was called Charger. And that was for a reason: he often charged cars and elephants. Although he was advanced in years he was still a BIG male tiger. And he did charge! I was glad I was on the oyher side of the elepant when he charged, and he stopped before actually attacking but the person on the side of the elephant which was charged exclaimed that he thought his life would end there.
BT, strange thing that tigers (and lions) never attack persons inside a car. It seems they cannot distinguish the people inside as separate individuals from the car. When I was in Botswana we camped in small tents and people inside were never attacked by lions, leopard or hyena's. Guess it is the same thing.
