Fortunately, almost immediately after the accident, an emergency room physician from Stanford happened by, as did firefighters from the Woodside Fire Protection District, said San Mateo County Deputy Sheriff Eric Sakuma
The bicyclist, who was wearing a helmet, was conscious and alert when taken to Stanford Hospital, said Deputy Sakuma, who has since visited her and reported that she has no memory of the accident.
Pending completion of an investigation, the Sheriff's Office has not released the name of either the cyclist, a 50-year-old Pacifica resident, or the driver, a 91-year-old Portola Valley resident.
The accident occurred around 11:20 a.m. when the cyclist, heading east on Alpine Road, attempted to pass her cycling partners and moved across the white line separating the roadway from its shoulder, and into the traffic lane, Deputy Sakuma said. She collided with the passenger-side rear-view mirror of an eastbound 1998 gold Cadillac, he said.
The driver, who was traveling at about 35 mph, was not injured, nor were there any injuries to the half-dozen other cyclists in the group, he said.
Witnesses told police that the Cadillac driver had been tapping her horn to warn the cyclists of her approach, Deputy Sakuma said. The cyclists were not racing, he added.
