What happens if the road has changed since last HD mapping ? If it can identify and not hit new or changed objects, why does it need HD mapping at all.
Every car on the network (so not only from one brand) with EyeQ4 chip harvests data for the map. As soon as there is a change, it will be reported by the car which detects the change first. The data is ~10kB/km so it works with low speed mobile connection. This would be more of an issue in deserted areas with no cellphone coverage.
The car can still drive without the map though. But having the map increases the safety quite a bit since the self driving software isn't mature yet. At these early stages it is possible that the car will fall back to the driver.
