TESLARATI(@Teslarati):🚨 Tesla FSD v14.3.9 has been very impressive in other ways. Yesterday in the Y L we had a pretty heavy rain and I was coming off a back road. FSD stopped short to allow a vehicle to have an easier turn, then took its own turn slowly to not impede oncoming traffic

I’m not sure how many people will agree but FSD v14.3.9 has given me more reasons to override acceleration than any update in recent memory Very hesitant to get up to speed, even on Hurry. Merging on the highway today required me to press the accelerator to get up to speed. Usually, FSD is good about using the on ramp to blend into the speed of traffic. That just isn’t the case here. There was also an instance that FSD chose not to pass an 18-wheeler on the interstate despite it traveling 39 in a 55. There were plenty of chances to get in the passing lane and it never chose to do so. I intervened and executed the pass manually. Respectfully, it feels like a grandma driving.
