There's enough control that it can steer for you, but I believe (and hope!) that it's not strong enough to override you if you know better than it does. With the current level of sophistication of self drive systems, we are still a very long way away from a car that should be able to override a human who is doing something on purpose. (though lots of warnings are a good thing!)I was thinking about that. In an ideal world, where the sensor was foolproof (and no sensor is foolproof), is the steering totally fly-by-wire such that it could prevent you from turning the wheel? I kinda doubt it...

I believe Tesla has indicated that this is the plan, if you try to change lanes despite the white arc, I think it's supposed to change to a red arc and vibrate the steering wheel. Not enough to prevent you from doing it (sometimes you need to do things that the sensors don't understand) but enough to know that it's trying to tell you something.I was thinking more in terms of the lane assist function I was playing with in the Audi a few weekends ago. With the TACC engaged, it actually exhibits the basics of self-drive... but knows if it hasn't received input from the driver and complains!
The Lane Assist watches the lane lines and keeps the car running in the centre. If you approach a lane edge, say with the intent to change lanes, and you haven't engaged the turn signal, it provides some resistance and vibration in the steering wheel. You can easily push through it, but you'd have to be really out of it to not recognize it was telling you something.
I don't know if the Blind Spot system tied into the steering as well, but it does turn on an amber light on the mirror edge. I wasn't going to test it THAT far...
