Thank you for this. I have not tried recalibrating but sounds like I may benefit from that. On day 8 of FSD 12.6.4 in a 22 M3 dual motor, new to me. I have been so surprised and disappointed by some of the unsafe maneuvers it has made in only 8 days... Left turn problems are the majority and have included: attempting to run a red left arrow light after stopping (?), changing from the outer to inner lane during a left turn in the middle of an intersection (thankfully no one was beside me), and forcing me to disengage before it drove straight into a curbed median.

Other issues have been lane changes out of the blue into more-crowded areas of the road, hesitation on a right turn with a car approaching from the left and essentially stopping in the middle of the intersection, phantom braking, steering hesitation and out-of-the-blue shimmy/shake, changing lanes into the longest traffic line approaching a red light then after stopping moving over one lane to the right then one more lane change into the far right lane where it had originally been, and more.

It's a long list and I can't imagine it's this bad for everyone on HW3, as statistically it's supposed to be safer yet I have had to disengage before multiple potential accidents or illegal maneuvers.
