Manufacturers of driverless cars promise that collisions will become a thing of the past.

Self-driving cars will be safer, they claim. With super sensors, laser and camera technology, they will be able to spot another car approaching, or a pedestrian in the road, and react far faster than a human driver could.

But when it comes to preventing collisions with kangaroos, engineers at Volvo have hit a stumbling block.

Crashes involving an animal cause the deaths of around 200 people a year in the United States. And about 20 times a day, a driver somewhere in Sweden crashes a car into a moose. Indeed, these types of collisions are the reason the Swedish carmaker has made large animal detection systems part of the design for its driverless cars.

Designed for a moose

The software, however, was designed with the prospect of a large animal such as a moose wandering into the road. So when the technology was tested in Australia it struggled to detect kangaroos.

If you drive on Australian roads, chances are, sooner or later, you will come across a kangaroo. And if you’re unlucky, you might be in one of the 20,000 accidents every year involving the marsupials.

In 2015, a team of Volvo Cars safety experts travelled to the Australian Capital Territory – a kangaroo collision hotspot – to film and study the roadside behaviour of kangaroos in their natural habitat. The data Volvo Cars collected was to be used to develop the first ever kangaroo detection and collision avoidance system.

“In Sweden we have done research involving larger, slower moving animals like moose, reindeer and cows, which are a serious threat on our roads. Kangaroos are smaller than these animals and their behaviour is more erratic. This is why it’s important that we test and calibrate our technology on real kangaroos in their natural environment,” Volvo said in a press release at the time.

Volvo Cars is developing a system that uses radar and camera technology to detect kangaroos and automatically apply the brakes if an accident is imminent.

However, the carmaker told Australia’s ABC News that after 18 months of studying kangaroos at the Tidbinbilla Nature Reserve in Canberra, it still hasn't been able to develop a reliable way to detect kangaroos on the road.

"We've noticed with the kangaroo being in mid-flight when it's in the air, it actually looks like it's further away, then it lands and it looks closer," Volvo Australia's technical manager David Pickett said.

There could be a simpler solution, though.
