The Federal government has expanded its powers to make laws and regulate the States and it citizens way beyond the powers granted to it by the individual states as a condition for joining the union and creating "The United States of America".
Please read the Federalist papers which were written by the founders in order to explain and guarantee the States and its citizens the limitations put on the Federal Government and the true meaning of such terms as "Establish No Religion" .
They have grabbed these powers by citing the pre amble wording "To Provide for the Common Good" or by proclaiming the Constitution is a "living changeable document" that no longer applies to todays society. In doing so not only do they assume powers not granted to them but find new powers and constitutional rights such as the right to abortion and unfunded mandates such as The Affordable Care Act. One California Democrat Congressman went so far as to publically say that Congress has the power to do what ever then choose and pass any law they want.
No one has ever been able to point out any wording or meaning that has changed since the Constitution was written that doesn't mean the same today. Transportation is still the act of movement by means other than foot and covers movement by any means not available when the Constitution was written.
