New Curtin research has found the introduction of driverless vehicles on our roads is likely to reduce drink-driving rates but could lead to greater levels of binge drinking.<\/p>\n
The research, published in the Drug and Alcohol Review,<\/em> found the increasing use of autonomous vehicles was likely to bring with it mixed health outcomes and therefore posed a challenge to policymakers in their efforts to minimise alcohol-related harms.<\/p>\n Lead author Research Associate Mr Leon Booth, from the School of Psychology at Curtin University, said by removing the need for a driver, autonomous vehicles were expected to substantially reduce rates of drink-driving.<\/p>\n \u201cHowever, this benefit may be accompanied by an unintended negative consequence in the form of greater overall alcohol consumption due to increased availability of affordable and convenient transport,\u201d Mr Booth said.<\/p>\n \u201cWe surveyed 1334 adult Australians, about half of whom reported being likely to use an autonomous vehicle after consuming alcohol, while more than one-third were likely to consume more alcohol if they planned to use an autonomous vehicle (AV).<\/p>\n \u201cLower age, more frequent alcohol consumption, a positive attitude to autonomous vehicles and a preference for using \u2019ride-share\u2019 AVs were associated with a greater likelihood of engaging in these behaviours.\u201d<\/p>\n Study co-author John Curtin Distinguished Professor Simone Pettigrew, from the School of Psychology at Curtin University and The George Institute for Global Health, said with autonomous vehicles expected to become available to the mass market around the world by mid-2020, the research highlighted an emerging issue.<\/p>\n \u201cOnce autonomous vehicles become readily available they could be used as a means of facilitating out-of-home alcohol consumption and more frequent bouts of heavy drinking,\u201d Professor Pettigrew said.<\/p>\n \u201cBecause the introduction of the vehicles will likely bring both positive and negative health effects, this represents a complex challenge for policymakers charged with reducing alcohol-related harms. A particular challenge will be the need to encourage the use of autonomous vehicles after drinking without encouraging drinking per se.<\/p>\n \u201cGiven that people\u2019s exposure to AVs has been very limited to date, more research will be needed as these vehicles become available on Australian roads, to assess whether people\u2019s drinking behaviours actually change in the manner they expect.\u201d<\/p>\n The research was co-authored by Associate Professor Richard Norman from the School of Public Health at Curtin University and funded by the Bankwest Curtin Economics Centre.<\/p>\n
