That's exactly how they explained the accident... Henri Paul's intoxication and Dodi's ego and stupidity. And the fact that neither Dodi, nor Diana, was wearing a seat-belt.I did watch most of this show the other night and have always believed this horrible accident was mainly caused by Henri Paul's intoxication and Dodi's ego. He refused to listen to the minimal security staff they had and it is really a shame that Diana was not travelling with British security of her own. Had she been, I think the outcome of that night would have been vastly different.
However, Diana could have had British security, but she refused it, so maybe she is a little to blame as well. Why trust the unexceptional Dodi with her welfare?
