I have to disagree, it is always funny to see any monkey damage a car of any type in a safari park.
What Joe Public are sometimes guilty of in Safari parks that can cause them damage like this to their cars, is that they generally try to get too close to the animals. If you take this incident, we have approximately two tons of large animal that is of the type that can be easily startled and to top it off, they have pretty crap eyesight; put that combination together with any animal and a car getting too close is literally an accident waiting to happen. Also, if the person in this incident was feeding or trying to feed the rhino, then I would have no sympathy at all.
I have watched rhinos (white) for many years and many hours in safari parks, and had a few 'heart in mouth' moments when they run right by the car, but keep your distance and they just generally ignore you.

The above shows what getting too close can happen...
