Tesla has the summons feature. My wife's car can park itself in the garage, and come out on it's own (provided you un-plug it). It can't un-plug itself. I think this is exactly for what Flash was talking about, tight garages or... showing off.
I see a lot of bad drivers out there. I'm seeing more and more that they are millennials. I think they go through withdrawal symptoms when removed from their phone for more than 2 minutes. How many people who txt and drive is really scary. This is the crowd that isn't interested in driving, and would prefer not to own a car. This generation is more used to their parents driving them around until their 22, so to have a computer to drive for them makes perfect sense to them. When you don't have to drive, you can check facebook on your phone, txt and look at cat videos.
For long drives and traffic, I love the autonomous driving on the Tesla. I can relax. Technically, you still have to pay attention and look out for white trucks with nothing underneath the trailer pulling in front of you.
I hate driving the 968 and the manual transmission in traffic.
Added comment, apparently the biggest issue with autonomous driving is the crazy traffic in California. Too many people driving on the shoulders at 60 MPH, cutting over white lines, motor cycles between lanes, people making their own lanes and torn up freeways. Apparently when the google cars get confused, they just stop. I think they learned this from Microsoft.
