FSD 14.3.12: user reports sudden roundabout stop and overspeed

📍 Reddit Tesla FSD

Unconfirmed: a user on a community forum reports two issues with FSD version 14.3.12, after updating. At a roundabout, the vehicle stopped suddenly when another car entered from the right, which nearly caused a collision. According to the user, the previous version did not show this behavior. On a highway, the system detected an 80 km/h speed limit but accelerated to 100 km/h in a specific section, so the user had to cancel FSD. The same user states that this version fixed an earlier problem related to red lights, although the post text is truncated.…

🔎 Why it matters: There is no official confirmation from Tesla: the post describes an abrupt stop at a roundabout and speeding past an 80 km/h limit with version 14.3.12, but it reflects the experience of a single user.
📈 Upside: According to the user, version 14.3.12 fixed an earlier problem related to red lights.
📉 Risk: According to the user, the sudden stop at the roundabout nearly caused a collision, and driving at 100 km/h in an 80 km/h zone forced them to cancel FSD manually.
