Reader John E writes in to give us a heavy dose of not news. "I was driving on the freeway with some friends and we saw a Samba De Amigo truck driving around," according to his e-mail. "I haven't seen anything on this anywhere else on the web, so I'm not sure what it's for." (OMG, does that mean we have an exclusive?!) We know what it's for John: making us seriously consider purchasing a commercial truck with bright red rims and Samba de Amigo branding, then having a custom horn installed that blares "El Ritmo Tropical" at anyone whose driving technique we disagree with.
