Sure, the Lane Departure Warning system will beep incessantly at you as 4200 lbs
of sheet metal and dead
cattle wander gently from one side
of the lane to the other, but as long as nothing unexpected arises (say, a curve, or for that matter, a curb), you'll meander
along quite gracefully, outwardly no different from the hordes
of cell - phone - addicted commuters
heading the same direction.
