I finally had a chance to give this firmware my running commute let's call it, which involves some local streets, some curvy highways and some fairly straight forward exit ramp transitions.
To be honest and say this is a a regression for me. On this one stretch of highway, there is a series of not to aggressive S curves, some of them tighter then others, but all on a main stream highway, so overall not that tight considering. Well, it's a good thing there was no one on the road with me at 5 in the morning, my car took the curve all the way to the extreme outer edge, I won't say it crossed the lane line, but it was certainly riding on top of it.
I suspect, the more I think out it, there is a torque limiter or something similar in the algorithm, that prevents the steering wheel from over steering by basically saying the most you can do for a given curve is say 20 degrees. And anything beyond that, it just try what it can until ultimately it will leave the lane and disengage auto steer as a failure ( this can be seen on most normal exit ramps)
Rock solid on straightways and such, but regressed a bit on curvy roads to me. Overall, I liked .44 better. The windshield wipers is a novelty, It sorta works, it was clearly pushed out before it was ready, so that Elon could get some form of a win before the year was out.
