Auto vloggers test out fuel-saving myths

Some of these hacks to save MPG are hilariously stupid, some dangerous, but the video is fun. The most useful fact, IMHO, was ripped from Mythbusters, a 6-10' drafting zone behind trucks.

The explanation of why manuals were once more efficient than automatic transmissions cracked me up! I know many SQUIDs who claimed it was them, not just three gears vs. five gear choice.
