We propose to use the average lifespan of a scrapped car (~19 years, https://www.ecologie.gouv.fr/politiques-publiques/vehicules-hors-dusage-vhu) and the average number of kilometres driven per year (~12,000 km, data on the French car fleet at 1 January 2025](https://www.statistiques.developpement-durable.gouv.fr/donnees-sur-le-parc-automobile-francais-au-1er-janvier-2025?rubrique=&dossier=1348) to deduce a lifespan in km of 230,000 km.
