Tweet This is a video from Volvo demonstrating their new Dynamic Driving system. How? The old fashioned way -- having a hamster in a little cage (possibly part of a table fan) screwed to the steering wheel of a 16.5-ton dump truck steer the thing up a cliffside road by guiding him with a carrot. Impressive, but it would have been even more impressive if you let hamsters work your new dynamic gas and braking systems too. Also, why is the video called 'Live Test 2'? Where's the footage from 'Live Test 1', and how much did you have to compensate the family of the hamster driver from that truck?
