11: Less Variety
Right now, with gasoline-powered engines, there are a huge variety of different car models to choose from. But as manufacturers limit their product lines to electric vehicles you will see an eventual decline in the variety of models. Cars like the Challenger and the Camaro will go to the chopping block in favor of a more universal model.
Crossover sales are hotter than ever, making muscle cars more of a specialty product. Would you want an automotive market where there is far less variety to choose from? With the rise in electric cars, this could be the case because of the limited range of electric vehicles.
