It is the responsibility of the driver to check to make sure the car has a clear path. In other words, you get out of the car, check to make sure everything is clear, then engage the feature.<p>The sensors are only there to tell the car when to stop (as in, to sense the back of your garage).<p>What if the guy activated regular vanilla cruise control and rammed into the truck. Would everybody be going off on Ford&#x2F;GM&#x2F;etc.? I doubt it.
