Report on use of HW2 assistance features today (note I am a new AP user overall, never had AP1). Overall, I like what I got today. Yes yes yes, it's late. Yes yes yes, it's not everything. Whatever. It's nice to wake up to a car that has new and useful features. Looking forward to future updates. Thanks, Tesla!
1) TACC performs fairly well. When following traffic, slows to stops and resumes fairly smoothly. Had a number of overhead highway signs cause a brief braking event. Had one instance of loud multiple BEEP, I guess the sound of a collision warning, and a much harder brake - don't know why, there were no cars in front of me, in any lane. In each case, TACC resumed normal speed on it's own. When engaging TACC well below the detected speed limit, acceleration is a bit too fast. Also, when space in front clears, TACC seems to accelerate a bit too fast to the max, a number of times causing unnecessary braking. When someone cuts in front of you, seems to take a bit of time to detect/react. I tried different distance settings and sometimes it feels like I'm either too close or too far and couldn't get a comfortable setting. Not sure why. When approaching stopped/slow traffic with no lead car, seems like detection of stopped traffic is way too late - always need to brake.
2) Autosteer did okay. At times, it jumped around in the lane a bit - a little unnerving. I intervened once in a 15 minute session of stop-and-go traffic in light rain. A couple of times, it would not engage, saying it was not available on the current road (the same road I was just using it on). Waited for a few seconds, tried again on the same road, and then it engaged.
3) General comments - road lane markings jump around quite a bit. Even while stopped, the lane markings tend to move around. Cars displayed seem to jump around a bit as well, the display makes it look like cars are changing lanes when they aren't.
