Thought this deserved it's own post.

Here is one of the more thorough videos on auto-pilot: https://www.youtube.com/watch?v=2geQ4hvvkNA

When auto-pilot is available then the steering wheel icon will appear grey to the right of the cruise control icon (aka. traffic aware cruise control TACC - "traffic aware" because see around cars 360 degree with sonar and handles things like lane changes in varying conditions -- speeds up/down/etc or handles things like seeing that a car is moving in your lane or turning out of your lane).

The steering wheel icon will be grey when you can enable auto-pilot. When you double pull on the 3rd lever (1=turn sign; 2=steering column forward/back adj).... then the steering wheel icon will turn blue. Blue means enabled.

If the lane lines are blue (not grey lines or not disappeared all together) then it is primarily focused and driving within the lines. Sometimes there is only one line - think curb or off ramp where right lane line disappear the car will then focus on the one line).

In example below from the video the camera *just* read a new speed limit sign and changed the driver info center display sign to 65.

I like how the vehicle will "lock on" to the vehicle in front of you and follow that in addition to reading the lines in the road. That fills in the safety gap should the lines in the road suddenly disappear.

It works pretty well but you can see the car "thinking" when that car you locked on moves to an outside edge of the lane (distracted) or changes lanes or turns a corner. It seemingly "locks on" when you are moving slowly like stop and go traffic or if you are at a stoplight. As well it does this if you go through an intersection and the tracking lines disappear. Lot of scenarios.

If you are in stop-n-go traffic it and the traffic speeds up the display will change to show blue lines and the car will go grey again. Meaning the car is indicating that the focus is now primarily on the lines.

Not perfect, and a great v1 but moving on to v2 and beyond will happen fast. We are witnessing the future right in front of us. Love how Tesla has guts, talent and passion to do this. Lead, follow or get out of the way.

I sure hope governments (city, state and federal) take an aggressive role in keeping lines painted on the road. There are some roads that look like they lines were painted once and never repainted. I have a feeling once autonomous cars are more popular, there will be wrecks due to lack of lines on the road.
