Study Finds Automatic Braking With Rearview Cameras, Sensors Can Cut Backup Crashes By 78 Percent (cbsnews.com) 161
A new study from the Insurance Institute for Highway Safety (IIHS) found that combining automatic braking with rearview cameras and sensors can cut reverse crashes by 78 percent. Rear automatic braking alone, which is an option in just 5 percent of new vehicles, is linked to a 62 percent drop in reported backup accidents in cars with that equipment. CBS News reports: Starting in May, all new cars in the U.S. will be required to have a rearview camera. Some automakers are going further by adding backup warning sensors and reverse automatic braking. For the first time, the Insurance Institute for Highway Safety tested that combination of technology. Two models -- the 2017 Subaru Outback and Cadillac XT5 SUV -- earned superior ratings. Four other vehicles scored an advanced rating for generally avoiding a collision or substantially reducing the vehicle's speed. But there's some room to improve. One vehicle did not stop automatically when backing up to a dummy car parked at an angle. Automatic braking in the front will become standard in most cars in 2022 but there's currently no plan to make it standard for backing up.

braking doesn't mean stopping, so if the brakes are automatically applied the closer you get to something the chances are they'll slow you down to a stop a few cm away even if they start to be applied 40cm away.

Engine braking is terrible on automatics. You have a fluid coupling between the engine and transmission that allows a lot of slip vs putting it in a lower gear and engaging it fully. Have you even driven a car with a manual transmission? This comment makes me think you haven't.

Sounds like the problem is the corners. Need additional cameras for checking to the sides for scenarios where you are turning and backing up and also when other objects are moving. And it does require much additional computation to predict movement of multiple objects relative to one another so bare bones automatic breaking is really about just automatically stopping when something is already in the warning area regardless of whether it is moving or not. To get to 100% you need to add side views and have
