Some Utah researchers believe they have discovered a way to better convey directions to distracted drivers than listening to a fellow passenger or a GPS system bark out directions.
The new system give a little tug on your right or left finger through the steering wheel when you need to turn. The University of Utah researchers stress that this is not meant to enable more cell phone talking while driving, which they say is unsafe. There's just a lot of background noise to tune out – from crying children, to the radio to street sounds.
It's just, perhaps, a better way to ensure that drivers follow directions and don't create unsafe situations from sudden lane changes, etc. It could also be a better system for those hard of hearing.
