Carpooling in France has gotten a boost because of recent transit strikes. Many people are discovering this way of getting around for the first time. One of the more popular French apps that lets people coordinate rides is BlaBlaCar. Unlike a taxi or ride-haling app, drivers only take passengers where they’re going already, for work or vacation. BlaBlaCar makes its money charging a 20% commission on each trip, according to BlaBlaCar spokesman Nicolas Michaux.
