A few drives and over 100 miles in with the new FSD v14 lite update and here are my thoughts: V14 lite was already quite good and this update brought some HUGE UI improvements which makes it feel so much better. Tesla has added a great Start Self Driving from park change where you now don’t have to confirm by pressing the brake pedal to start FSD from park. Seems like a minor change but it’s a huge quality of life improvement. Tesla has also added the same parking options tab as AI4 cars, when approaching your destination it pulls up the tab to show you your parking options at destination. It shows the blue P and you can press it mid drive as well. Something else to note is Curbside has now been changed to Pull Over just like AI4 FSD v14.3. The Self Driving App has been added in this update just like AI4 cars, it tracks your overall percentage of FSD usage. Doing the math on my current usage/odometer it seems like the tracking started when I installed 2026.8.6. The Self Driving app shows you instructions on how to use FSD too as well as monthly stats. This new update has also brought streaks! Just like AI4 cars it tracks your continuous streak of FSD usage. It also shows you how many days in a row you have used FSD. Got a 100 mile streak tonight and it showed confetti just like AI4. Highway performance is SO good still. Keeps a consistent speed with no unnecessary lane changes and I saw zero left lane camping tonight. It handles high speed curves so perfectly and doesn’t ping pong and it feels so dialed in. Dare I say almost as good as AI4, almost all the way there- just wish it would accelerate stronger in hurry onto the highway when merging from the on ramp. Great lane choices and passing decisions. No traffic so it sat at 2mph slower than it used to when no cars around in standard and hurry but if a quicker car would come by it would speed up a bit. DMS might also be slightly more sensitive but it was dark out, will confirm with some more driving later today. City streets: this update is similar than before but seems to be slightly more confident around city streets. Hurry was a bit quicker than before but I wish it would accelerate slightly stronger in hurry profile only. Really good yellow light performance on the three I encountered and had smooth braking and no overreactions. I did however see the weird turn signal bug for the second time ever tonight at a traffic light so this is still present with this update as well as the slight steering wheel wobble at around 40mph and still way improved over v12.6.4. They definitely improved the way it leaves stop signs and lights though, slightly more linear and smooth acceleration from a stop. Obeyed both no right on red signs I encountered too. Dips and speed bump speed is perfect as it was before too. Most importantly, FSD v14 lite feels so much safer than v12.6.4. Parking might be slightly improved in this build where it took a better approach angle like I mentioned it needs to in the previous build reviews. It still doesn’t straighten out wheel at the end which I would like to see changed. It also still “double stops” when almost done with a parking job backing up to a supercharger space. Speed might be a tad quicker than the last build as well but will get some more parking in later today to confirm my findings. Overall, this update (2026.20.6.10) brought some massive UI changes, quality of life improvements, and really made this update feel like v14 even more. Absolutely incredible what they’ve accomplished with v14 lite on HW3 cars. Feels like I got a new car. Thanks @Tesla_AI and UI teams for all the hard work getting this out and I really hope it rolls wide soon!


When I went to the cardiologist to do some heart tests the doctor made me run on a treadmill at full speed for 15 minutes at the max speed, I think it was like 13 or 15 mph. I felt like my heart was in my head and couldn’t even talk for like a minute or two and this guy is yelling and screaming out of excitement


Hello @FedExHelp @FedEx I have a package with 6 bottles of wine shipped from California that has been at your Kennesaw hub since last Thursday at 4:08am. Could any living human possibly contact me about this package that is apparently lost now please.



Been driving a HW4 car all day. Holy cow. Blown away at the performance compared to HW3 V12
