The DOT will run heath care???

Sometimes political cartoons are good. Other times, they just fall flat on their faces. Take this one, for example:

First, its message is not precise: The "folks who run our transportation arteries" are the various Departments of Transportation (and possibly Departments of Motor Vehicles). It is inconceivable that the DOT will be put in charge of health care. Of course, if the message is, "Government: Keep out of our bodies!" or "Government: We don't want socialized health care!" then that could make a little more sense on the sentiment. However, if closer to the latter, it then becomes somewhat of a case of knee-jerk libertarianism. Let me explain:

One of the problems with the idea of government keeping out of public life is that we would unlikely have such things as the interstate system that we today take for granted. The massive public subsidies have created both good (the interstates) and bad (massive traffic problems caused by increased use of interstates) outcomes. However, if the interstate and state highway systems were not subsidized by government, then the cost of travel and interstate commerce would increase. (Note: the states cannot tax interstate commerce, but they could charge tolls on roads, thus increasing the cost of travel.) Many people who are anti-government/pro-free market conveniently forget this point.

Finally, as a bumper sticker, proposing no alternative to the [perceived] status quo (or future) is okay, since the point of a bumper sticker is to get a POV across while remaining legible by the person tailgating you through morning and afternoon traffic. This bumper sticker fails the pithy-and-legible test that most bumper stickers must pass.

Now, looking at the overal tenor of the piece, the car is a massive piece-of-work. Is this saying something about the state of the American auto industry, or is it a visual necessity in order to have a bumper larger than the driver's head in order to put on that not-at-all pithy nonsensical statement?
