Teslas (while much maligned and deservedly so) can already drive pretty well on most well painted and high traffic roads. Granted it is very conservative and often I take control just to avoid other drivers honking at me for taking too long to turn. But this article mentions L4 autonomy. L4 still allows for geofencing and human control. Tesla is already pretty much L3, borderline L4. I think it is realistic to say L5 won't exist until radical change to our infrastructure is made but to say L4 won't exist in our lifetimes... I mean, I suppose if you're 80 years old already. I also think it draws too radical a conclusion in the article. The conclusion is from the author. The people from Ford explicitly said they think that it will be developed independently and Ford will be able to buy it instead of having to make it themselves. Which is very different than "it won't happen in our lifetime." It seems they didn't decide to stop research because it is not possible but because oters can do it cheaper.
