Looks like he's fine, went to hospital for observation in case of
complications due to concussion, but he's looking forward to the
next >> race.

Excellent, good to see the safety devices doing there job.

They certainly do. One of our V8 guys(Jamie Whincup) had a nasty
crash,

in the last meeting's qualifying where he says his Hans Device
stretched 2.5cms. Not sure what is an acceptable stretch for those
things, or indeed for a neck, but i'm pretty damn sure that i don't
want my neck being strecthed by an inch. :)

True, having your neck stretched is not generally a genetic
inheritance. ;)

Are you sure they were referring to the longitudinal stretch rather
than that produce by a nodding action.

I know, the Hans is designed for the nod. None the less in an accident
the driver will stiffen his neck just as he would without one. So if
the Hans device, which is designed to remove a fair chunk(presumably)
of the force when the head tries to take off from the neck, can
stretch an inch, the forces on his neck would have been very, very
severe without one.
Don't know what percentage of force a Hans device can remove from the
neck, but i think it has be a fair bit, as it got pushed through to
just about every decent series, despite a lot of driver resistence at
the time, if you recall.
Of course, maybe Mr whatshisname who invented it, had lots of buddies
in the FIA. :-)
