Ms Rose died in August 2005 after being struck by a vehicle in the Civic bus interchange. The car was being driven by a 14-year-old youth and was being chased by police. A coroner found police actions on the night had not contributed to the death of the 21-year-old Ms Rose.

In November 2006, Amber Westin ran a red light while evading police in Woden, killing 82-year-old Heather Freeman, of Campbell.

Ms Rose's parents, Frances Rose and Ross Dunn, said yesterday the death of four people on Saturday night after a police pursuit had again demonstrated the need for more strict guidelines before police began a car chase.

Late on the night of December 18, 2007, Christopher Miatke, then aged 17, drove his car into a tree on Majura Avenue, in Ainslie, after fleeing detectives who had been trying to arrest him for the previous three months. The L-plate driver was paralysed and sustained massive head injuries when his car was destroyed in the crash.

Only two weeks ago, police pursued a vehicle which failed to stop for a routine traffic check in Calwell. Speeds up to 140km/h were reached during the one-minute chase. Police had lost sight of the vehicle before it crashed into a house in Ellerston Avenue.

Mrs Rose said yesterday it was appalling there had been six deaths in the ACT in less than five years involving police pursuits.

''We don't have the death penalty in Australia, but people die.''

Because of the prominence of her dead daughter's name, ''We believe we must continue to act. We know police hate being on the front page of The Canberra Times. So keep it up.''
