The vehicle boats a pickup-truck first, a powered tailgate that can be raised and lowered from the key fob. This system has force sensors (Principle 23 – Feedback) that reverse the motor if resistance is detected (such as pinched fingers) or if there is an object resting on the tailgate.
Ford has included blind-spot monitoring in its trucks for some time now. GM is finally adding it to the Silverado, but unlike the Ford system, GM is not integrating them into the taillights (Principle 1 – Segmentation). This is to spare the owner the expense of replacing this expensive system in the event that a taillight gets smashed.
