Oxymoron

Does it make sense to drive a huge SUV with an American flag on top? I saw an example of this in the form of an Escalade EXV recently (is that what it's called? It's the huge one) and just could not understand it. Do these people even think before putting the flag on? "Oh hey, let's show my patriotism by putting a flag on a gigantic example of how much oil I use." It's the equivalent of going on strike while continuing to do your job.
