Across the UK and Europe, cars are steadily growing longer, wider, and heavier - a trend critics have nicknamed ‘carspreading’. SUVs in particular have surged in popularity, with their market share rising from 13% in 2011 to nearly 60% by 2025. Buyers praise them for visibility, practicality, comfort, and a sense of safety, and carmakers favour them for higher profit margins. But cities like Paris and Cardiff are pushing back, arguing that larger vehicles worsen pollution, increase road wear, and heighten risks in collisions. In Paris, after parking fees for heavy vehicles were tripled, the authorities have reported a two-thirds reduction in their numbers. Cardiff plans similar measures, gradually lowering weight thresholds for higher permit costs. Supporters say cities are too constrained to accommodate ever-bigger cars, while critics argue families rely on them for space, mobility, and accessibility. With many European roads narrower than modern vehicles, the debate highlights a growing tension between personal convenience, environmental responsibility, and urban safety.

More than ten million Britons are at a higher risk of dementia because they live near a busy road, scientists have concluded. Those living in big cities are up to 12 per cent more likely to develop dementia as a result of traffic fumes, according to a study of more than six million people in Ontario, Canada. The closer people live to heavy traffic, the higher the risk. The scientists said that their findings were ‘of real public health significance’. They called for homes to be built further away from traffic, and for levels of traffic-related air pollution to be further reduced. Half the population of Ontario lives within 200 metres of a busy road, and 20 per cent within fifty metres: these figures are likely to be higher in Britain.
