I don't think any item is "ignorable" if you are about to run directly into it. I get that the computer might not be able to track every road sign or object to the left or right of the car.

Still do you want your car to directly hit a sign, litter or barrier? Why not have a second smaller system like the backup warning sensors most cars have to avoid hitting non-movable objects taller than 6 inches?

But in curves (or directly before them) you have plenty of stationary items that you appear to happily drive into in a few seconds. They're right ahead, after all.

Also note that despite all the hype surrounding those features you're still supposed to pay attention as a driver. Marketing and manuals tell very different stories here and the liability question is purely answered by the latter.

If I was at highway speeds and a bag blows in front of me? Yes I want to hit it. Slamming on the breaks might kill me.
