Episode Title: Traffic Tricks

Air Date: 2014-08-07

Overview:

The subject is everyone's favorite topic of discussion besides weather: traffic! The MythBusters determine whether a roundabout (or rotary) is better than a four-way stop sign, if it's faster to drive than fly when your trip is under 400 miles, and whether it's better to change lanes or stay put in heavy traffic.
