Superchargers and turbos have been heavily used since WWII. Made high altitude piston engine performance a reality. They are simply not going away. Yeah nothing displaces displacement but the cost in weight and idle fuel use make it problematic.
Yeah, turbos are awesome and necessary at aircraft altitudes. Note, though, there is still a good percentage of normally aspirated small aircraft produced. The lower cost to build, operate and maintain normally aspirated aircraft engines is the reason, even with a turbo's the hugely important power to weight advantage when flying.
For an automobile, a turbo is an entirely unnecessary, problematic and expensive component to break. I drive normally aspirated vehicles on the highest elevation and steepest grades in the US (I-70, Loveland Pass, Berthoud Pass) and never want for more power.
There is every reason to believe aviation's well documented higher cost to build, operate and maintain turbo engines also applies to cars.
