I get something you could consider worse: letters designed explicitly to look like communications from the DMV. I got an absolute DELUGE of these about a year ago from various companies wanting to sell me auto warranties. Phone calls too along the same lines: very official sounding, no company name given, just to contact some person.

The letters were downright devious. The company letterhead was designed specifically to look at a glace like the state official emblem, the contents were all white paper, no photoshopped images (cheaper to produce and more accurate to the real deal, win win I guess) and the marketing materials were designed to look like pre-filled official forms, except when you actually read it you realized it was application for that bloody warranty.

I can't fucking believe it's legal to send shit like that. You're two steps from impersonating the Government. I could totally see someone a little further on in years (or just not paying attention!) thinking they had to respond.
