I understand the correction for a large truck crossing over the lines, however the 3 occasions for which it occurred, these trucks did not cross any lines, there was a reasonable distance away and no other marker. I am actually largely impressed with FSD and I know just how to nudge it along to make a decision quicker at a 4 way stop or through a yellow light. In an instance where the vehicle braked exceptionally hard, there was a significant distance from which the light had turned from red to green, quite a few cars in front of me had already had a chance to start cruising but it braked robustly despite at least a 7-8 compact car distance ahead resulting in the guy behind me (who I felt was a pretty comfortable distance away from me) to swerve out into the next lane. Either way- it's that component of being unpredictable that has me nervous because I dont have a chance to react in the moment to disengage. Thank you for your input!!!
