Siew was cycling on the pavement along Pasir Ris Drive 8 in October 2009 when she was hit by construction cables coming from a nearby worksite.
The court found Hyundai 100 percent liable for the accident, which left her warded for more than 2 years at a stretch, and still remains warded.
Siew suffered minor injuries from the accident, but claimed that accident was so serious she suffered Post Traumatic Stress Disorder.
Siew had initially sought $26 million in special and general damages, which included medical and hospital expenses.
The $8.645 million which she was eventually awarded includes sums for loss of future earnings, present and future medical costs as well non-medical expenses.
