High visibility clothing may be invisible to modern car technology, study says

High-visibility clothing may make pedestrians and cyclists invisible to modern braking technology, a study has suggested.

Automatic emergency braking (AEB) systems, which are fitted to all new cars, automatically apply the brakes if the potential for a collision is detected and the driver fails to respond quickly enough.

But a study by the US-based Insurance Institute for Highway Safety (IIHS) indicated the systems may have a “blind spot” for reflective items.

Researchers conducted trials involving a crash test dummy and three cars travelling at 25mph: a Honda CR-V, Mazda CX-5 and Subaru Forester.

The Honda and Mazda hit the dummy while it was wearing reflective strips, while the Honda also failed to slow down when a high-visibility jacket was put on the mannequin.

The Subaru slowed down in all tests except when the dummy wore reflective strips in very low light.

IIHS president David Harkey said the results suggest car manufacturers “need to tweak their pedestrian automatic emergency braking systems”.

He said: “It’s untenable that the clothes that pedestrians, cyclists and roadway workers wear to be safe may make them harder for crash avoidance technology to recognise.”

“This is a worrisome blind spot,” he added.

Mazda said in a statement: “Road safety for everyone, including those in and around our vehicles, is a top priority for Mazda.

“Our engineers are continuously working to improve Mazda’s crash avoidance systems and are already using these latest IIHS results to further assist us in this work, with special consideration for nighttime pedestrian scenarios.”

Honda and Subaru were approached for a comment.
