They basically all did it, some just got caught earlier. I said it back when they all hit on Volkswagen: It is not like that all the other companies have found the magic trick to get emissions miraculously down, and just VW was to stupid to find it somehow, and had to cheat. This time it’s Cummins they caught. All you have to do is look closely, and you’ll find that they cheat, because in reality, none of them have that magic trick.
