Paris has transformed its streets under mayor Anne Hidalgo, slashing car traffic by over half since 2002 while expanding cycle lanes sixfold. Bikes now carry more than twice the journeys of cars, turning the city into a global model for urban mobility. Hidalgo, stepping down after 12 years, declared 'The bike beat the car' as she leaves office. This Sunday's mayoral election is a referendum on cars, pitting Hidalgo's successor against a car-friendly rival.

The city's shift proves pushing out cars improves life for most inhabitants, cutting accidents, noise, and pollution while creating vibrant outdoor spaces like 300 pedestrianized 'school streets' and café terraces. Retailers' fears of lost business were unfounded, as Paris ranks globally among the top four cities for business, according to Oxford Economics. Car ownership is dwindling, with only 28% of households owning a vehicle in the dense core. But the suburbs need better transit, with plans for 68 new metro stations by 2031 and improved bike connections.

The revolution faces challenges: managing delivery vans and aggressive cyclists, and controlling tech firms' data. Autonomous vehicles could further reduce car dependence, starting in London this year. Paris proved the car isn't essential, setting a precedent others will watch closely.
