Tesla’s new Enhanced Autopilot has a known bug causing wobbly road lines on the instrument cluster


Since Tesla started pushing the update to introduce the first phase of Enhanced Autopilot to the rest of its fleet equipped with the second generation hardware (first 1,000 already had it), we have received several bug reports.

One of the most common bugs, and also the most bizarre, results in inconsistent displays of the vehicle renders and road lanes on the instrument cluster.

While the new Enhanced Autopilot might not appear much different from the first generation Autopilot since its actual features are currently less complete than the previous version, the system is built on a completely different platform. Not just because of the new hardware with 8 cameras instead of one, but also with the automaker’s new ‘Tesla Vision’ image processing system.

Adapting the Autosteer and Traffic Aware Cruise Control (TACC) features to the new platform requires some tuning.

Currently, several owners reported that the render of the lead vehicle tracked by TACC can sometimes start lagging and the road markings can unsteadily move from side to side.

Here’s one of the best example we have seen so far:

Tesla told us that they are aware of the bug and they are working on a fix.

Fortunately, it doesn’t appear to have an effect on the performance of the Autopilot beyond the display making it look like the lead vehicle is doing the wiggle dance:


A more important issue is the pitch angle of the cameras. Some owners receiving the new Autopilot update are not able to complete the calibration of the camera and have to get the pitch angle fixed at their local service center.

CEO Elon Musk said that a new update is coming and it would improve “self-calibration”:

Hopefully, it will result in fewer people needing to get the pitch angle fixed by Tesla’s service center. Musk said the fix will be to adjust image crop dynamically in order to make cameras more robust to pitch angle.

For those without the issues, it was described to us to work as advertised. Model S and X owners with experience with the first generation Autopilot said that it’s currently about 80% to parity with the older system, but it should catch up as soon as Tesla removes the 45 mph speed limit on Autosteer after receiving more data from the fleet.

From there, Autopilot on the new hardware suite should quickly surpass its predecessor and Tesla should start introducing the new Autopilot features promised in Enhanced Autopilot.
