How to force lane changes with Tesla Enhanced Autopilot (EAP), using HW3 in the UK

Подробнее о видео

I've recently added Enhanced Autopilot (EAP) to my 20 month old Tesla Model Y RWD. In this video I revisit auto lane changes which is one of the features of EAP. While automatic lane changing works well when using 'Navigate on Autopilot' (where you enter a destination in the navigation), I was unable to force a lane change with the indicator.
Following comments on my previous lane change video (see ) I was told that I needed to fully depress in the indicator to force a lane change, whereas I had just been giving the indicator a light (half) touch.
So in this video I drive on some dual carriage way (A34) and motorway (M4) to test out lane changes again when on standard Autopilot and navigate on Autopilot.
During this drive, I also experienced my first phantom braking and Autosteer strikeout and also some examples where Autopilot made some poor decisions.
Others have reported that the 2025.26 over-the-air update has made Autopilot worse. I'd not experienced any differences until this drive, which could explain why Autopilot didn't perform as well in this video. Obviously, a future OTA update will sort out these issues.
The vehicle in this video is a 2024 Tesla Model Y RWD (MCU3/HW3) with the 62.5kWh (60,5 kWh usable) LFP battery and at the time of filming this running on software version 2025.26.7.
This video was filmed in August 2025.
