#4 misplaced use of AbstractVehicle in SteerLibraryMixin?

[Craig Reynolds]

Perhaps references in SteerLibraryMixin to type
"AbstractVehicle" should be replaced with "Super".
(Which should probably be renamed to something like
BaseVehicleClass.) I think they just mean to refer to
generic vehicles and not specifically to
AbstractVehicle. As Artem Baguinski points out, the
"mixin" approach says this template is agnostic about
base classes.
