To make the trucks easier and safer to drive, they'll have an optional lane departure warning system that will vibrate the driver's seat in the event the truck wanders out of its lane. Similarly, a forward collision warning system will also shake the seat in the event of an obstacle ahead requires the driver's immediate attention.
