As of today, AP2 is still missing the following AP1 features:
* Auto-dimming touchscreen
* Automatic windshield wipers
* Autopark - perpendicular
* Display cars in other lanes
* Side collision avoidance
* Side collision warning
* Sign recognition
It's also still steering itself off the road in places AP1 worked fine. There are videos over at r/teslamotors on Reddit or the TMC forum.
