A recent study highlights that dust generated from car brakes is potentially more harmful to human health than exhaust pollutants, based on its impact on human lung cells in laboratory conditions. Despite the concerning findings, discussions around the results emphasize other important aspects of vehicle emissions, such as tyre pollution and the environmental implications of electric vehicles (EVs) versus internal combustion engine (ICE) vehicles. Several commenters mentioned the role of tyre pollution, regenerative braking technology in EVs helping to reduce brake dust, and the potential shift towards mandatory regenerative braking systems to mitigate harmful emissions. Additionally, some proposed using ceramic brakes as an alternative for lower dust production and better performance, raising questions about the overall environmental benefits of EVs.
