I've owned a Tesla Model S for 3 years and have never been impressed w/ any software updates.
In fact I can say I dread every time they do an update, because it seems to degrade the performance of the car.
If anything, they add silly video games and cosmetic visual nonsense (fart sounds) that have no material value to the car.
From the latest updates, I'm now being babied to stay in my lane, use my blinkers to change lanes or else get pushed back to my own lane, and get false positive loud shrieks about the impending crash into the car in front of me... LAME UPDATES...
Give me a real update that makes a significant difference to the car...
Now w/ the latest update from 12/11/2019 ... I'm now getting odd screen blackouts in the past 2 days that's unexplainable.... while driving... that last a few seconds... ????
