Stuff I see on the road when driving into work

So this SUV was in front of us when driving into work the other day. I wasn't sure if the owner was being ironic, funny or mean.

When I see a HUMMER SUV, my first reaction isn't "what a great alternative, earth-friendly vehicle"...

Then I thought, well, maybe it's a company car (I believe there is a company by that name here that does air quality inspections) ... but that didn't make too much sense if they are in the air quality business.

I'm stumped by it, yet got a good laugh at the same time.
