Her death is a classic example of the way we say, after almost every death: if only. If only she had hit the seat at a slightly different angle. If only she had been thrown forward 10mph more slowly. If only she had been put in an ambulance immediately. But the biggest if only, in Diana’s case, was within her own control. If only she had been wearing a seat belt. Had she been restrained, she would probably have appeared in public two days later with a black eye, perhaps a bit breathless from the fractured ribs and with a broken arm in a sling.
