I don't think this is going to (or should) stop people applying for AI invented parents.
However.. I do think that the cost of applying for a patent should be a lot more to avoid spamming.
It's like the guy who wanted to use a computer to compose all possible combinations of notes in music with the purpose of copyrighting all music. I'm like.. didn't you also just break the copyright for all existing music?
Anyway, I don't mind people using computers or AI, but patent trolling and spamming shouldn't be financially feasible. Make the product first or fuck off.
Unexpected or not, it should do its best to stop or avoid the obstacle, not drive into it.
An autonomous vehicle shouldn't ever be able to actively drive forward into anything. It's basic collision detection that ought to brake the car here. If something is in the position the car wants to drive to, it simply shouldn't drive there. There's no reason to blame the obstacle for being towed incorrectly..
