Advanced driver-assistance systems such as adaptive cruise control are less likely to be in use on curvy roads than on straightaways, according to a study released this summer by the Insurance Institute for Highway Safety.
It is a concerning finding since the crashes that such systems are meant to limit are more likely to happen on curvier roads than on straight ones, said Wen Hu, senior research transportation engineer for IIHS.
"The safety benefit would be maximized if drivers could use [the systems] or these systems could work on these sharper curves," Hu said.
The study drew on test data from the Advanced Vehicle Technology Consortium at the Massachusetts Institute of Technology based on how 39 drivers used 2016 Land Rover Range Rover Evoque and 2017 Volvo S90 vehicles over the course of four weeks. Bo…
