You know when you've had enough - the bear says so

If the fluffy bear mascot on your car dashboard starts talking, drivers could be forgiven for thinking they have had a bit too much to drink. But Japanese scientists have come up with a high-tech critter to be the judge of that. They have created a robotic satnav bear to help drivers find their way through traffic and also caution them if it detects they have been drinking. It’s good to know that the world’s best minds are hard at work solving the globe’s most pressing problems. The bear is designed to use its arms to point drivers in the right direction, which, if nothing else, should be a life saver for people who do not know left from right.
