注意到特斯拉老有非常近cut lane, 查一下是這樣；開車小心；

Why do Tesla vehicles sometimes make sudden or close cuts (lane changes) near SUVs or trucks on the freeway at high speeds?

?

This behavior is likely related to Tesla Autopilot or Full Self-Driving (FSD) system behavior, and it has been observed and discussed by many users. Here’s a breakdown of possible causes:

---

1. Autopilot/FSD Overcautious or Overaggressive Logic

• Tesla’s system may overreact to large vehicles like trucks or SUVs in adjacent lanes.

• It may "think" those vehicles are drifting too close and initiate a lane change or evasive maneuver.

• Sometimes this results in jerky or seemingly unsafe lane changes, especially at high speeds.

---

? 2. Camera Sensor Interpretation Errors

• Tesla relies mostly on cameras (vision-only) after phasing out radar and ultrasonic sensors.

• In certain lighting, angles, or shadows, the system may misjudge the position of nearby trucks/SUVs.

• Large boxy vehicles can cause false positives in lane departure or collision avoidance logic.

3. Blind Spot Behavior Lane Merging

• When merging or overtaking, Tesla may cut in closer than a human would in front of a truck/SUV if it calculates enough space, but without the courtesy humans usually show.

• Some drivers report that Tesla cars change lanes aggressively to avoid being "boxed in", especially around large vehicles.

4. Software Bugs or Version-Specific Behavior

• Tesla continuously updates FSD/Autopilot via over-the-air (OTA) software updates.

• Certain versions may introduce or worsen behavior like:

  • Close cuts in front of large vehicles.

  • Inaccurate modeling of adjacent lane behavior.

  • Overcompensating for "phantom" vehicle drift.

? 5. Edge Case: Drafting or Misjudged Gaps

• Sometimes, Tesla may attempt to change lanes behind or in front of a truck to optimize flow (like in adaptive cruise or Navigate on Autopilot).

• If the truck is accelerating or decelerating slightly, this may result in the Tesla cutting in abruptly.

Conclusion:

If you or others are noticing sudden lane cuts near trucks or SUVs, it’s likely an FSD/autopilot behavior issue involving perception, logic, or prediction modeling. Tesla logs all driving data, so if this seems dangerous, it’s often reported and addressed in future updates — but it's still not foolproof today.
