A new study from the American Automobile Association (AAA) has found that rain can severely impair advanced driver-assistance systems (ADAS). Similar to how highway traffic slows to a crawl when there’s a sudden deluge, modern safety equipment can have real trouble performing when a drizzle becomes a downpour.

On Thursday, the motor club organization released findings from closed-course testing that appeared to indicate some assistance suites had real trouble seeing through bad weather. AAA reported that 33 percent of test vehicles equipped with automatic emergency braking traveling collided with a stopped car when exposed to simulated rainfall at 35 mph. The numbers for automatic lane-keeping was worse, with 69 percent drifting outside the lines. Considering the number of times the people writing for this website have anecdotally criticized ADAS for misbehaving in snow, sleet, rain, fog, or just from an automobile being a little too dirty, it’s hard not to feel a little vindicated.  (Read More…)

No longer content with just crashing vehicles into walls or poles, the Insurance Institute for Highway Safety has turned its attention to the ever-expanding buffet of new technologies found in today’s automobiles. Driver assistance features ease the driver’s workload and make for comfortable highway cruising, but all systems aren’t made equal.

For its test of “Level 2” autonomous features — meaning, specifically, adaptive cruise control (ACC) and active lane-holding — IIHS selected five premium four-doors. The test group consisted of a 2017 BMW 5 Series with Driving Assistant Plus, a 2017 Mercedes-Benz E-Class with Drive Pilot, a 2018 Tesla Model 3 and 2016 Model S equipped with Autopilot, and a 2018 Volvo S90 with Pilot Assist. Given that each model garnered a “superior” IIHS score for automatic emergency braking, they seemed like choice candidates for a comparison test.

The results, as you’d probably expect, were a mixed bag. We’re not at the technological finish line yet; not by a long shot. (Read More…)

Lane departure alerts and blind spot monitoring systems can significantly reduce crashes if consumers use the features, according to two recent studies by the Insurance Institute for Highway Safety. While this information falls into the no-brainer category, rarely do we get specific metrics on these particular technologies.

“This is the first evidence that lane departure warning is working to prevent crashes of passenger vehicles on U.S. roads,” explained Jessica Cicchino, IIHS vice president for research. “Given the large number of fatal crashes that involve unintentional lane departures, technology aimed at preventing them has the potential to save a lot of lives.” (Read More…)
