Volvo admits its self-driving cars are confused by kangaroos

Swedish company's animal detection system can identify and avoid deer, elk and caribou, but is yet to work against the marsupials' movements

Volvo's self-driving car is unable to detect kangaroos because hopping confounds its systems, the Swedish carmaker says.

The company's "Large Animal Detection system" can identify and avoid deer, elk and caribou, but early testing in Australia shows it cannot adjust to the kangaroo's unique method of movement.
