A doctor has to declare a person dead, paramedics can't do it. In all cases it makes sense to transport the body to the hospital where the person is pronounced dead by the doctor. Otherwise the family may argue in court the paramedics did not try enough to save the person.
Usually in reports, if someone dies at the scene but is only officially declared dead at the hospital, they'll write a phrase like 'was declared dead at the hospital'. This report says instead that he was transported to the hospital 'where he died from his injuries'. Double-checking, media articles at the time uniformly describe him as dying at the hospital, and at least one says that he died in the afternoon ( http://sanfrancisco.cbslocal.com/2018/03/27/tesla-crash-inve... ) while the accident was at 9:27AM, so either traffic in the Bay Area is even worse than I remember, they like to spend hours doing CPR on a corpse, or he did in fact survive the crash and died at the hospital in a literal and not legalistic sense.
Not legally true, as a paramedic. EMTs and paramedics are able to declare people dead in certain, albeit limited, circumstances, sometimes involving telephone / radio consultation, sometimes not.
