""Lowering speeds does reduce fuel consumption, especially at highway speeds, because aerodynamic drag increases rapidly as speed rises. A reduction of around 10 km/h can realistically lead to fuel savings in the order of 5-10 per cent, depending on the vehicle and driving conditions.""
""From a purely technical perspective, the idea is sound and can even help with improving road safety. But the bigger question is whether it's practical to implement.""
The global fuel crisis is impacting Australian households as oil demand and prices rise. Energy analysts suggest strategies to reduce fuel reliance, including work-from-home policies and encouraging public transport, walking, or cycling. The International Energy Agency recommends allowing remote work and reducing speed limits by 10 km/h to cut petrol use by 5-10%. Professor Hussein Dia supports the idea, noting that lower speeds decrease fuel consumption due to reduced aerodynamic drag, but questions the practicality of implementing such changes in Australia.
