That's the thrust of a study by the National Highway Traffic Safety Administration ( NHTSA) showing that motorists followed speed limits when offered financial perks.
The study, conducted by researchers from Old Dominion University in Virginia and Western Michigan University, focused on 50 people who drove cars equipped with GPS trackers designed to monitor speed. Drivers who didn't go over the limit received $25 each week.
Another new driver safety technology being testedThe study sheds more light on intelligent speed adaptation (ISA) systems that determine if someone is speeding by using GPS to link a vehicle's position to digital maps that include local speed limits. In addition to GPS, some newer systems use cameras to read speed signs. The ISAs, according to a recent report from the IIHS and the Highway Loss Data Institute, then could warn drivers that they're going too fast or even automatically slow the car. Typically, ISAs notify drivers of speeding by one of the following:
- an audible or visual alert telling the driver to slow down
- a haptic alert via the accelerator that makes it increasingly more difficult for the driver to depress the pedal
- reducing engine throttle to automatically decelerate a vehicle
