It seems impossible that they could have it be fully autonomous to the point of not needing a steering wheel though. You can tell an autonomous car "take me to the mall", or "pull out of the garage", but there are so many edge cases that seem like they would still require manual control. How do you tell it which spot to pick in a parking garage? Or how do you tell it to, say, drive on to a lift while inside a buildin…

Self driving cars don't use GPS, it is not reliable or granular enough.

At all? How would it drive to the mall on the other side of town without GPS?

It better be fully autonomous if you've ever seen how rear-wheel drive performs in a north-eastern snowstorm. Sure, there's a lot of weight over the back wheels but that sounds crazy to me as the default.

I couldn't believe it was gonna be a fully autonomous car long-term until I saw the empty dashboard in the video: http://i.imgur.com/XcUjuDv.jpg

"95%+ of the time it will be driving itself" That's a shitty metric. Does it mean it will need intervention every 950ms for 50ms?

If you want to willfully misinterpret what was said, sure.

I'm hoping we'll indeed see some tweaks to the nose -- it looks like a blank waiting for a cut-out to fit a grill and will leave the car feeling nearly-finished if it stays that way for production. Only bit that wasn't really a home run for me (for a pre-production, anyways). But otherwise... shooting for autonomous-first at launch will be interesting indeed. How would that effect the opinions of the folks now on the…

That mask started to grow on me: it makes the car look like a spaceship, and even more importantly, it sets it apart from all other cars out there.

It's like the hatchback-shape of the Prius. I don't think anyone does actually find that attractive, but it's a great design to tell everyone from a distance that you're a better person than them.

'The rear-wheel drive cars will be able to go zero to 60 in less than 4 seconds. ' I don't believe that.

It’s a known fact that electric cars have superb acceleration mainly because they deliver all power from the beginning, in contrast to internal combustion engines that need to reach certain rpms to achieve the same thing. Even if it’s 6 seconds instead of 4 it still is an impressive number for a car at that price range.

6 seconds at that price point is pretty normal for a car portending to be a sporty. For example a CLA is in its price range and does 0-60 a tad over 6 seconds.

Eh, you may be defeating your own argument there. The main reason that front-wheel drive is better in slick conditions is more weight over the wheels in the typical front engined car. Rear wheel drive may actually be better if the battery pack is sitting on top of it.

With the oblong steering wheel they mentioned and spaceship like controls, I'm thinking they just don't want the steering wheel sticking up in front of that awesome view. Perhaps an airplane-line yoke? There is the problem of the steering wheel needing to go multiple revolutions, but there do exist some variable ratio steering systems where you might limit rotation to +/-90 degrees but the wheel travel is speed dependent. There are options besides fully autonomous.

As for the lack of instruments, I rarely look at much other than the speedometer while driving, and if the car can read the signs and help regulate speed for me, I may not even need that. My non-Tesla car has an audible chime at 50 and 25 miles to empty, so I don't even need to look at the fuel gauge.

Reminds me of a joke:

- "I read half the book... It was completely incoherent."

- "Which half did you read?"

- "Every other word."

Don't rule out HUD gauges projected onto the lower left of the windshield. 95% autonomy in a commercially available car by 2018 is very unlikely IMO.
