Perhaps I'm unreasonably dense, but I do not see the link (direct or otherwise) between 'it works well for me under the following circumstances' and 'it will work well for (almost) everyone, under all (reasonable) circumstances'. The former can be true, without any guarantee of the latter. Given all the hyperbole and promises that have been made thusfar, it's hardly surprising that folks are inclined to be skeptical, particularly if their own experiences are as poor as many in this thread indicate.
What I do agree with is that cars are going to be allowed to drive themselves, irrespective of how well they can do it, because the politicians and the bureaucrats apparently are unable to resist the siren song of 'progress'. That much we've seen in SF with Cruise among many other plraces. Whether this is a good thing is a different question entirely...
