Auto braking is already in use in the trucking industry and phantom activation a problem.
If turning and their is a large object at the side of the road, it will apply brakes.
A large dip in the road that puts the truck on a downward incline will also activate the brakes when the sensor detects to approaching upside of the dip.
Duct tape is the cure for the phantom sensor activation.
Add that to my list of uses.
