No, I'm not referring to the Grateful Dead fans of Seattle. I'm referring to the STITA (Sea-Tac airport to Seattle and vice versa) taxi drivers who are not allowed to carry passengers in both directions. Quite ridiculous. I sent an email to askthemayor@seattle.gov and Mayor Nickels actually responded to my question on his show, but his answer was they're "working hard on it." Where's the proof, and why is Seattle lagging behind NYC and Boston, where they have been using hybrid taxis for some time now?
