> What're the reasons for NOT including AM? The only thing I found is mention that including it will "hinder progress". What progress? It's always about manufacturing cost. Automakers will trim a BOM to save 60 cents on a car. If they have the data that AM is not a 'requested'/desired feature when purchasing a car then of course they would want to trim it. Also AM radio imposes quite a few extra design constraints in terms of EMI, in a vehicle that by definition is extremely electrically noisy.
