Maybe it's closer than you think.
University of Michigan has a project called "Integrated Vehicle-Based Safety System"
The project director at the University of Michigan says the
equipment could help car and truck drivers choose the path of least
danger, when either stopping or changing lanes would pose risks.
The Integrated Vehicle-Based Safety System is supposed to go
beyond the collision warning detectors seen in some luxury models.
It would take data from multiple sources to help drivers assess
their options.
