Some 25% of respondents knew nothing about driverless vehicles, whereas 14% did. The average 5-point Likert scale response was 3.12 (SD = 1.05), indicating intermediate expertise. Some 42% of respondents used autonomous vehicle sources such as public transport, 47% had no experience, and 11% were doubtful. The survey items’ Cronbach’s alpha score is 0.873, indicating strong internal consistency and reliability.

Malaysia faces a particularly pressing issue of abandoned vehicles (AVs), as the country currently lacks comprehensive legislation for managing ELV. On the other hand, countries such as the US, Japan, Belgium, Korea, and China have well-established ELV management policies. In light of this, a pilot study assessed the public’s perception and attitudes towards ELV issues and regulations in Malaysia. The study gathered participants’ views on surrender, deregistration, disposal costs, incentives, recycling, and ELV regulations. The questionnaire used in the study was based on the findings from a previous report. The data were analysed using SPSS version 27, based on 40 interviews with diverse participants. The results of the study revealed three primary themes: “AV and its ELV”, “ELV disposal procedures”, and “ELV regulation and conflict resolution”, with 1...
