Unless someone convinced the driver to commit suicide, I don’t see how their deaths could have been anything other than an accident.
A drunk driver doing a hundred is just death waiting to happen.
You know, a lot of people refuse to admit that at the time of her death, Princess Diana was on a downward spiral. She was messing with married men, stalking one of them, toying with the idea of converting to Islam, deluded about the reality of her role in life, and was clearly out of her mind at the time.
Suggesting that she was murdered is a way of excusing her from being held responsible for her actions. We’re told not to get into a car with a drunk driver and to wear a seat-belt is what anyone in a car should be doing.
