"May never happen" is such a cautious statement that to argue against it means "will certainly happen", and that's a pretty extreme position to take -- so extreme I would call it techno-utopianism. I'm still waiting for my flying car, but you are already promising me a thinking car, when there are so many obstacles, each of which could sink it:
- researching it may not be feasible
* because it becomes a waste of engineering resources to continue the research
* because almost self-driving cars may be good enough
- even if researching it is, it may not be economical because
* political resistance or liability laws prevent mass rollout
* the cost of building and maintaining required infrastructure is too high
* not enough car purchasers may want it
- researching it may not be feasible
- even if researching it is, it may not be economical becausereply
