🚘 Car

Today's cars in France are mainly combustion-powered (petrol, diesel), although electric vehicles are making slow progress.

However, whether electric or combustion-powered, the car remains a highly inefficient means of transport: On average, it's enough to move an 80kg human being in a 1200kg metal box.

It's a bit like making lunch for 10 and then throwing away 90% of the food, or deciding to heat the whole block rather than the inside of each of the 10 houses.

Finally, it's important to take into account both the use (the kilometers traveled) and the construction of this vehicle made of over a ton of various materials.
