Volvo collision avoidance system press demo fail

Bosses at car manufacturer Volvo were left red-faced when a press demonstration of their new collision avoidance system failed.

Volvo had arranged for photographers and journalists to see their new safety feature in action preventing a car from crashing.

The technology works by using a sensor on the front of a car which calculates if a crash is imminent and  automatically applied the breaks leaving the driver safe.

Or that's the theory. Unfortunately the demo didn't go to plan and as you can see from the below video the S60 car smacked straight into the back of a truck it should have avoided.

But all was not lost… at least you can see the windscreen wiper continues to function even after the smash.
