Here is the image of hands on mode, which I guess would be the same for the vehicles without 2.0. There is a single lane and the vehicle ahead, I've seen a car and a truck icon in the view.
Here is the ProPilot 2.0 view in hands free mode (blue). It will show the left and right side lanes (if any).
View showing truck icon
View showing the diamond lane (HOV lane), and the amber glow on the lane line is the blind spot indicator due to the vehicle in the blind spot area (which are shown as transparent).
When the vehicle ahead is slower (I believe the range can be set in the settings) than your set speed, you can press the button on the steering wheel to start the lane change. The car will perform the turn signal and the lane change, you need to have your hands touching the wheel for safety. The wheel is capacitive, so you don't need to turn it like torque based steering wheel systems. I noticed you can also engage the turn signal yourself and it can perform the lane change, if you are patient enough. Though I can't tell exactly when that function is available. When there is a navgiation destination set, it can ask to initiate the lane change into the exit lane.
After using it for a bit, it is kind of like sitting on the couch and the couch is traveling down the road, since the car is pretty good at being soft on bumps and fairly quiet. A bit surreal, but very helpful.
