"I felt like the Camry Hybrid was too subtle for the message I wanted to put out there."

"I wanted to have the biggest impact that I could, and the Prius puts out a clearer message."

Well, make sure you drive it around a lot so people will see how much you care.

IN THE COMMENTS: Susan says "Of course the message can get off track if you're caught driving your Prius at 100 MPH while you're under the influence." She links to this:

Al Gore's son was pulled over for speeding on a California freeway early Wednesday and arrested on suspicion of possessing marijuana and prescription drugs, authorities said.

Al Gore III, 24, was driving a blue Toyota Prius about 100 mph south on the San Diego Freeway when he was pulled over...

The deputies searched the car and found less than an ounce of marijuana along with Xanax, Valium, Vicodin and Adderall...

Let's be fair. It only says "possession," not under the influence.

Anyway, this is a big downside to driving to express the message that you're superior. You'll probably screw up and then people can mock you. (Here's an old post about bumper stickers in a similar vein.)
