Cadillac is about to change what driving is like for the better.  Get ready for the first true hands-free driving system for the highway.

The system won't let the driver completely tune out.  It monitors the driver's face for open eyes and to make sure you look out the windshield reasonably frequently, no napping or reading.

A green light bar glows on the steering wheel when the system is active.  if the driver's attention is off the road for too long, the light flashes a reminder:  Eyes front!  It flashes red if you ignore reminders to look forward.  The Detroit Free Press has more.
