The Inaccuracy of Advertised Gas Mileage and the Benefits of Hypermiling
TLDR Advertised gas mileage on car stickers and commercials is often inaccurate due to the EPA's reliance on auto manufacturers for testing. However, hypermiling techniques can significantly improve fuel efficiency by driving conscientiously and using techniques such as coasting and cutting the engine early.

Hypermiling is a technique that can significantly improve fuel efficiency, with some drivers achieving up to 100 miles per gallon in a Toyota Prius.
13:22
Hypermiling techniques can be used with any car to improve fuel efficiency, such as driving conscientiously, avoiding quick acceleration and braking, using cruise control, driving at lower speeds, and minimizing the use of air conditioning.
16:33
Hypermiling techniques include coasting and cutting the engine early when approaching a parking space, turning off the car if idling for longer than seven seconds, ridge riding to make yourself noticeable to other drivers and avoid puddles, and maintaining a slow steady pace and anticipating traffic lights to avoid using brakes.
