> For something different - cars going at slow speeds emit more fumes and consume more fuel. There's research that refutes this for 30mph -> 20mph limit lowering. https://haveyoursay.tfl.gov.uk/lowering-speed-limits/widgets/31529/faqs#question9170 https://haveyoursay.tfl.gov.uk/lowering-speed-limits/widgets... " Do slower speeds cause congestion and pollution? Imperial College London's research into the impact of 20mph speed limits suggests they have no net negative impact on exhaust emissions. Results indicated clear benefits to driving style and associated particulate emissions. The research found that vehicles moved more smoothly, with fewer accelerations and decelerations, than in 30mph zones, reducing particulate emissions from tyre and brake wear. We have undertaken an Environmental Evaluation and are satisfied that the lowering of speeds will not have an adverse impact on the environment or air quality. The Environmental Evaluation recommendation was that no air quality modelling was therefore required. "
