SMU Associate Professor of Psychology Christie Napa Scollon commented that the Car-Free Sunday initiative, which is being extended for another year in 2018, boosted one's’ “well-being”. “First, it encourages physical activity which is excellent for physical and mental health. Also, Car-Free Sunday provides a space for people to have fun together and, really, happiness is all about being with others," said Associate Prof Scollon, who is a regular participant. "At a broader level, the initiative can also improve the health of the wider community by increasing civic engagement, reducing car emissions and encouraging long-term interest in physical activity," she added.
