The autonomous vehicles Volvo is testing in Australia are having issues identifying kangaroos in the road.

The way that kangaroos move has confused the automaker’s 2017 S90 and XC90 models that have been used for testing in the country, according to the BBC.

When kangaroo’s are in mid-flight, whilst hoping, the vehicles have trouble detecting where the animal is because the cars use the ground as a reference point, according to ABC.

Approximately 80% of animal collisions in the country involve kangaroos, according to the Australia's National Roads and Motorists' Association. Further still, more than 16,000 kangaroo strikes each year have created millions of dollars of insurance claims, it said.

In 2015, Volvo's safety engineers began filming kangaroo behaviour in a nationally recognised hotspot for collisions.
