This study is conducted to identify the car user’s practices and behaviour, with focus on six specific areas: car ownership profile; travel pattern and exposure; cost of vehicle ownership (CVO) – trip, legal, risk and aftermarket; knowledge and awareness in maintenance and retrofitting; perception and involvement in road crashes; and perception on End-of-Life Vehicle (ELV) initiative. As a continuation of the previous study dubbed as “the automotive ecosystem in Malaysia”, this study took the Klang Valley (KV) car commuters as the representation of the above- mentioned practices and behaviour. As current data and other studies suggest that the ownership of cars in Malaysia is among the world’s highest, this study is vital to explain the status quo of Malaysia’s car users’ ownership experience and its relationship with the effort to create a safe and sustainable road traffic system in the country. Though this study is not intended to generalize the scenario of automotive consumerism in Malaysia by using Klang Valley as a proxy, certain findings were well within expectation (e.g. ownership profile, ownership cost), some can be used as comparison with other studies (e.g. weather studies, travel pattern and exposure), or can be used as preliminary findings for future exploration (e.g. non-work and long-distance travelling, unreported accidents). As certain areas in the current Malaysia’s automotive ecosystem are already in the transformation phase (e.g. VTA and NCAP initiatives for safer and highly roadworthy cars) or still under the discussion and planning phase (e.g. ELV), academia and researchers should continuously provide useful findings and propose strategies in order to create a safe and sustainable automotive ecosystem in the country.
