Cross-country cyclist killed

A cyclist traveling across the country with four Yale classmates was hit
by a
car and killed Sunday on U.S. 60 in Henderson County, police said. Rachel
Speight, 21, of Houston, Texas, lost control of her bicycle in the
westbound
lane of the highway, crossed the center line and collided head-on with an
eastbound car driven by Kathy Foster, 40, of Henderson, police said. The
accident occurred about 10:35 a.m. The impact sent Speight and her bicycle
into
a cornfield, said Kentucky State Police Sgt. Terry Whittaker. Speight, who
was
wearing a helmet, was pronounced dead at the scene. The five cyclists were
traveling from Yale University, in New Haven, Conn., to California,
Whittaker
said.

Not too much detail in the article. What made her lose control that much
that she crossed the center line and into oncoming traffic??
