“Because the Constitution puts the ultimate power to regulate commerce in Congress, rather than the states, the degree of state legislation's interference with that commerce may be weighed by federal courts to determine whether the burden makes the statute unconstitutional. * * * [T]his Court pointed out years ago `that a State cannot avoid the operation of this rule by simply invoking the convenient apologetics of the police power.' Burdens upon commerce are those actions of a state which directly `impair the usefulness of its facilities for such traffic.' * * * A burden may arise from a state statute which requires interstate passengers to order their movements on the vehicle in accordance with local rather than national requirements.”
