Diana died because her driver was blind drink and because she wasn’t wearing a seat-belt.
There is no mystery here.
People refuse to accept it I guess because she’s stll seen as a victim and therefore not responsible for what happens to her. The simplest explanations are often the hardest to accept.
That’s what makes me wonder. Diana didn’t drink alcohol and she didn’t like being around people who had too much to drink. You would have thought she could smell the alcohol on her driver a mile away.
