I received the HW2 EAP update last night (and installed this morning). When I "started" the car I got a "driver assist features not available" message so I did a 68 mile freeway drive to give it some calibration time. First thoughts: TACC was immediately available. A vehicle in front of me was tracked and I slowed accordingly Vehicles pulling into and out of my 6 car gap was handled well. When a large pickup trucked passed me on the left, the TACC reacted and hit the brakes. The truck was never in my lane. On the return trip, the sun was in front of me. TACC was slowing down for the shadow of overhead road signs. Once doing so hard enough that I got a collision warning. When I had vehicles too close behind me I disabled TACC as having the car brake for no reason would not be safe. If the right side safety wall on a bridge was too close the lane, TACC would slow for a second. EAP: I couldn't test EAP as I was never in a situation where I could safely do 45 on a 65mph road. I tried on a freeway frontage road but it told me that AP wasn't available on that road. Looking at the lane lines on my dashboard, they were really dancing around. If that's an indication of how lane keeping would perform, it doesn't seem safe in this release.
