This is my second post on TMC - after watching the forum for many months, and then I pulled the trigger on my first Tesla MS 60 as a commuter car replacement in October. I was one of the weird cases that had to make a choice between AP1 and AP2 after I ordered my car. I chose AP2 on faith, and have been driving the car myself since delivery in early December. I have enjoyed driving it so much that I have not been too concerned about the wait for EAP. Yesterday I got the update, and took it for a quick spin right after the update installed. I received no camera calibration messages that I can recall, and everything worked immediately. This morning I found enough slow traffic that I could engage about 20 miles of Auto Steer with EAP this morning on the North Dallas Tollway. TACC was already working great, and when the traffic slowed down then I engaged Auto Steer. Turned on fine, and even followed the car in front of me through a new construction zone (a common occurrence on the NTTA). The only concern I had is when the car would hug the right side of the lane, seeming to be pretty close to the cars in adjacent lanes, but still within the lines. The steering wheel is constantly moving, making micro adjustments - even at very slow speeds. It almost seems (totally guessing here) as if the front camera is the only one driving the show right now, and that the system is sensing the input from the side sonar (radar?), but is not fully utilizing the cameras on the side pillars in order to see the cars in adjacent lanes. I am making an un-educated guess here, but it seems like the side pillar cameras are not yet fully activated at this point, and that is causing the uncertainty and waffling in the lane. The "lane dancing" feels like the car is trying to hard to play the game, yet has one hand tied behind its back. I never felt like there was any danger, it felt more like a new driver that was uncertain and needed guidance. It seems like there is a key ingredient missing that is pending and yet to be added (hardware and/or software), and when it is turned on, then Auto Steer will be ready for primetime. TACC worked perfectly for me all day. I am having a hard time thinking about driving in any other way now - especially with my 100 mile round trip daily commute. I came to a full stop multiple times behind cars at red lights, and the car smoothly continued on with traffic several minutes later when the light changed, just like I would have done.
Recommendation based on today's experience with TACC - I would turn off the TACC as you approach crowded city driving, especially if you are transitioning from a fast highway (70 MPH) to a more dense city environment with traffic signals. The speed will stay locked at 79 MPH unless you turn off the TACC or adjust it downward for the new speed limits in town. Cars leaving the lane in front of you could cause you to GO REAL FAST depending on where you last left the cruise control. Got a little coffee on my shirt this morning as a result (LOL) but it served as a great reminder of how much fun it was to get through some of the worst traffic in North America. For the first time in a very, very long time, I am excited to go tackle the tollway in the morning. This is why I bought the car, and I know that it will get better over time.
