Hidalgo's plan is to remove the motor vehicle infrastructure that has choked the capital city for the past 60 years. Cutting back on the use of personal motor vehicles will help clear the city of its smog problem, and replacing pavement with parks will help cool the city. 

Slate reported that between 2001 and 2018, the use of cars within Paris dropped by almost 60%. During that time, car crashes fell by 30%, while pollution also decreased. According to the United Nations, heat-trapping gases were reduced by 25% between 2004 and 2018. 

Closing streets around schools has made them safer and cleaner for kids. Instead of noisy, air-polluting cars surrounding schools, kids and teachers are using the roads. Cleaner air has even been linked to higher test scores from students. 

Getting people out of their cars and traveling by foot or bicycle has drastically changed Parisian daily life for the better as the city continues to divest from its formerly car-centric ways.
