1: Car sales have steadily declining for 5 years, and truck sales have soared. Trucks include pickups, SUVs and crossovers.
2: Truck salesin 5 years have gone from equal to cars, to 2 trucks for every car sold.
3; It would cost billions of dollars to develop the next model as auto sales require, and by the time ready to market, it may never be possible to even recover development costs, let alone make a profit. It makes sense to quit developing a product that will probably loose money.
