People join the American Automobile Association because they think it's a nice way to get Triptiks, traveler's checks and emergency towing, but what most members don't know is that AAA is a lobbyist for more roads, more pollution, and more gas guzzling vehicles. AAA weighs in on highway funding, suburban sprawl, mass transit, car design and safety, air pollution, and global warming. Almost without exception, critics say, it advocates policies that damage the environment and endanger health.
