More than eight out of 10 drivers still drive alone in their car in the morning during rush hours in Île-de-France. Drivers were “alone on board their vehicle” in 83.8% of the more than 500,000 vehicles observed around 10 French metropolises using cameras.
This represents an average of 1.24 people per vehicle, "still far from the target" for France's official roadmap for its reductions in CO2 emissions. The number of carpoolers would need to triple to achieve this objective.
