I don't know about any other Tesla software than my own. The software on my Y is at least 5 years behind Kia. I traded in a 2018 Kia that had much better driver assist features. They worked reliably and consistently. Blind spot detection worked well, alerted me both with a chime and blinking yellow lights in the appropriate mirror. Lane departure warning was always just right. My headlights moved with the steering wheel, which was really nice, pointing where I would be going based on the current front wheel angle, rather than where the car body was pointing and of course changed from high to low beam appropriately. My windshield wipers were automatic and kept the windshield clear, detecting rain and operating at an appropriate speed. The smart cruise control allowed me to adjust the following distance over a reasonable range. And I could maintain a 100% safety score, (for insurance purposes), because the car didn't wander off and get itself in trouble, requiring me to slam on the brakes, make sharp turns or correct for the car doing things because it was apparently frightened by the shadow of a bird flying overhead, heat mirage or other phantasm.
