1) As the economy contracts and industries shut down, if prices were to rise, they may not be able to start up production again. Especially in the face of competition from advanced solar (roll-to-roll printed amorphous silicon) and sucking gasoline out of thin air (currently at demonstration stage).
2) Parts count. Cars have too many components. 3D printed basalt fiber/ABS body with electric drivetrain.
3) Beware graphs that are capped at 26 mpg.
