2020 is the final year France will switch to daylight saving time, before definitively choosing between winter or summer time. Citroën decided to take advantage of this news during the final transition to summer time, which will no longer take place in 2021. The Lost Hour is a radio broadcast, released only on FM freeway (a radio station for road traffic), broadcast right at the moment of daylight saving time. Precisely at that time, in the middle of the night, we lost an hour. An hour's drive where many things could happen, but which have now fallen into the limbo of a parallel universe.
