I guess it is because Rally Estonia organizers have paid enormous effort in order to transform the roads into conditions as they are in Finland. They have built trampolines and jumps in order to get the character of the roads suitable. Also for example the ''Truuta'' area which adds a custom designed superspecial stage effect into one of the most famous stages, creating a new dimension to spectating a special stage.
Nevertheless, so frustrating spectacle to see such innovators of the sport forced into unthinkable solutions :/
