If it's nearly as good as Audi's lane keep/traffic assist tech in real world usage, I am excited!
I have an Audi with the lane keep assist, and I don't know that it's all that much to get excited over. It's handy if you're planning on driving drunk or distracted, but that's about it. Put another way, I don't think it's anywhere near sophisticated enough to be called "semi-autonomous".
Volvo has an autonomous driving feature as good as Tesla's? I didn't know that. I agree that these systems are not nearly good enough to be called autonomous or even semi-autonomous. They do work "very nicely" but that's about it. Nicely. If you need to take your eyes off the road for something it can really come in handy and be a life saver. But I certainly would not depend on it at this point in time. It's just not good enough yet. Unless, maybe, you're in a Tesla (or Volvo now?).
