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.
