WASHINGTON – Long-distance drivers and highway travelers praise cruise control, but a recent study warns drivers may want to rethink its use.
Using a driving simulator, VINCI Autoroutes and the Centre of Neurocognitive and Neurophysiological Investigations put 90 drivers to the test. The participants included an equal number of men and women in three different age groups.
In addition to cruise control, speed limiters that set a car’s maximum speed and are not typically used in the U.S. were part of the study.
Drivers were presented with four scenarios. They went through each three times, with cruise control, with the speed limiter and using neither device.
Researchers found the attention capacity of drivers was reduced. Not being attentive reduced a drivers’ abilities to respond in dangerous situations. Specifically, the study participants couldn’t merge into traffic as easily due to difficulty adjusting their driving speeds.
The study also found the following:
