I doubt if speeding was involved here.  To me, it looks like a few mistakes
that can easily be chalked up to inexperience.  First, inattentive/drifted
off the road to the right.  It happens to everybody, but more frequently
when you are inexperienced.  Second, didn't re-enter road correctly.  Most
likely, she just immediately jerked the steering wheel to the left, which is
the instinctive reaction, and the wrong thing to do.  Probably got the right
rear tire hung on the edge of the road momentarily, which caused the vehicle
to aim itself into opposing traffic.  At this point, the situation was all
but recoverable.  To say the driver over-corrected and drove off the right
side of the road?  Well, I'm not sure too many drivers of any experience
level could have recovered at that point without leaving the roadway, so the
point is kinda moot.

But anyway, inexperience alone was more than sufficient to cause this
tragedy.  I really doubt speeding was a factor, at all.  It's easy for most
to ASSUME that something like this was caused by speeding, as most drivers
don't realize the momentum that accumulates in a vehicle AT the speed limit.
As soon as the car drifts off the road and goes sideways trying to re-enter,
it doesn't matter whether the car was speeding or not.  At the speed limit
alone (or even under the limit), an inexperienced driver is in deep
oo-doo.  -Dave

There's no mention in the article about speeding being a factor.  It
sounds like a classic case of not paying enough attention to one's driving.
