I actually looked it up. 35 MPG is perhaps generous when their 2021 cars are averaging 30.9MPG, but it’s a low sample size.

Finland imports a lot of used cars but: “An average car in the fleet 12.6 years of age” that suggest the car actually lasts to ~25.2 years. It’s not that simple because again they are importing and exporting used cars.
