Snapshot, the usage-based automobile insurance program, offered by Progressive calculates rates based on three criteria that are largely out of a driver’s control. Mileage traveled, time of day you drive, and speed of braking. That last category is an opportunity for Prius owners, old and new, to showcase the habits they’ve picked up while paying attention to the car’s feedback display. Among Prius drivers, the display has sparked changes in driving behavior out of a concern for saving gas.
“Once you start making fuel consumption more visible, you have something that comes to the forefront of people’s minds instead of lurking in the background,” said Sarah Darby, a researcher who studies energy feedback technologies at the University of Oxford’s Environmental Change Institute. The monitors “show the consequences of your actions,” she says. “This gives you feedback that alters actions, and encourages you to try and improve things.”
In the Prius and other hybrids with energy displays, drivers can see what specific actions mean for their mileage. In some ways, it is like children learning to color in between the lines, with the teacher standing over their shoulders. Aggressive acceleration after a stoplight — that’s bad. The monitor will show mpg going down. Suddenly slamming the brakes — also bad. Coasting to a stop — good. That tactic lets the engine shut down, saving gas.
Looks like insurance rates could be an added bonus.
