It was in the paper and according to the reporter who spoke to the witnesses it looks like the people in the car are at fault.
I could not see if the bull was in musth, neither did I see the video but in all probability the people in the car did not read the body language of the elephant. Most elephants in the park are rather used to vehicles allowing you to get very close to them indeed. However, knowing the tell-tale signs of agitation when you are in the comfort zone of an elephant goes a long way ensuring the safety of yourself and your passengers.
In a minivan one time when an elephant charged an oncoming vehicle and switched his attention on us so I had to back up a couple hundred yards before the bull decided to let us be. There was no time to see if the bull was in musth and fortunately we had no vehicles behind us, therefore we made our escape good.
