Clearly, any kind of always-on automation that is responsible for braking, must be able to gauge the strength and importance of obstacles. For example, driving through that grass slowly and carefully, is ok. If there is a wire hanging across a road, then that is definitely something to stop for.
I'm thinking that a very good visual AI would be necessary to make distinctions like this; radar won't even see a wire, I don't think, and to lidar, it would look a lot like the grass. A touch-sensitive coating on the car would probably be a good idea too, so that the car can tell when if it is starting to scratch its paint on what it thought was an insignificant obstacle, like a branch.
Simply not looking at obstacles in one area because of the difficulty of rejecting false positives is a terrible idea, and demonstrates that that AI is not ready to drive.
