Horrible news, I hope he makes a good recovery and is able to live a long and healthy life. It seems he's lucky to be alive and, whatever his injuries, a long recovery process seems likely, and this could easily be the end of his career. But his age and fitness should serve him well if this is survivable.
The vagueness of the original statement obviously makes your mind race, but it must have been fairly soon after the accident and of course they need to respect his privacy and be conscious that he might have close family and friends who hadn't been notified yet.
The pictures of the wreckage are distressing, but remember - cars are designed to crumple, to absorb as much of the impact as possible before it reaches then inhabitants.
Really makes you think about how fragile life is, if you needed a reminder.
