Issues with FSD + Hitch mounted bike rack

[docowen]

First off…love my truck and FSD. Im just over 5,000 miles and since FSD release probably 70% on FSD. Overall I have been pretty impressed with FSD other than similar issues to those that others have been reporting.

This past weekend I drove around 300mi with my hitch mounted bike rack and one MTB. It was like FSD forgot how to drive especially on the highway. The truck was not only hugging the center line but frequently crossing over it to the point of needing to take control. Or when traveling in the right lane it would cross over the center line then decide it just would switch to the left lane without signaling. I was afraid to keep FSD engaged when other cars were around for fear of an accident or being thought drunk. It didn’t do too bad on two lane roads but turns were significantly more jerky than typical. I drove again this morning without the rack and everything seems back to normal so I am assuming the rack was the issue.

Has anyone else experienced this with either the CT or other Teslas?

I have on my '17 TMX with two bikes on a hitch mount. It was a fair number of OTAs ago tho.

I have experience this with a bike on back, although not as extreme. Backing up and parking is a pain. I wish Tesla would add a “Bike Rack” mode so the computer knows what’s back there. It’s not an obstacle or car following too close! Maybe we need a right-in campaign requesting a bike rack mode?

It is wierd for towing too. Of course FSD is desabled for towing but I thought the plug for lights did that. I drove the other day with the tailgate down and NO FSD if the gate is down because of no rear camera. So, if that camera is blocked, with a bike rake ... that camera is still sending data to FSD.

Hmmmm.

I dragging up this old post because I experienced this the other day on the most recent FSD version. I thought something was wrong with my calibration. Now I think FSD was confused by the bicycles being so close to the camera. Two big issues expressed themselves. The truck could no longer maintain what lane it was in - hovering on the center line, then left, then right. All over the place. The second and scarier issue was the speed. The truck started accelerating Rapidly and to speed limits not safe for the roads it was on. In one case it got up to 65 mph on an exit ramp with a stop sign at the end. It was not going to stop. I think what was happening is that it interpreted the bikes as a vehicle on my ass and it was trying to get away from it. That might also be why it couldn’t keep in a lane. I’m just speculating. Still, they do need to add a towing feature that effectively disables that rear camera so FSD doesn’t lose its mind.

put painters tape over the rear camera, fsd works fine after that. (drive with tonneau open for rear view)

Yeah they haven’t addressed obstructed back up camera yet.

Same experience here with my e-moto. It absolutely does not like it being back there.

Yes!!! just drove 600 miles from NV to WY Tuesday and had to keep hands on the wheel the whole way, truck ran across the rumble strips ( actually kept going until I took control back). Happened in all lanes also crossed into adjoining lane without signaling. The steering wheel was jittery the whole time as well. I called Tesla support about 1/2 way while I was at a SC and they did a hard reset and suggested it would recalibrate after 10 miles or so, it didn't of course. Also while manually driving lane departure avoidance didn't work as well, never corrected when I would cross the lane markers, also didn't give me a blue line or audible warning.
Glad to hear it wasn't my truck only, but sad to hear it is an issue. Anyone having the issue while pulling a trailer? I think I'm going to revert to standard cruise control while I have the bikes on the back ... BUMMER

Interesting theory.

I've had the driving over the left line issue, without anything obscuring the back camera, and I wonder if it's condensation or general dirt causing the behavior.

In my Model Y, about 5 software versions ago, FSD + bikes on hitch rack = erratic lane changes on highway (very, very abrupt with super aggressive swerving).

In contrast, the Cybertruck + FSD + bikes on hitch rack made very smooth and highly appropriate lane changes. My observations are over a few drives in city, rural highway, and interstate drives.

Yes, I am dealing with lack of lane centering with this config on the Cybertruck. I need to drive the Model Y for a comparison and see if it is still "crazy" on FSD with hitch rack or not.

Really happy that using FSD on two-lane highway (Salida to Denver US 285) I am able to use turn signal to deliberately cross (dashed) yellow line and pass pokey slow traffic when appropriate.

Yes…multi lane highway is significantly worse. I almost don’t notice when I’m on a two lane highway but it cannot be trusted on multi lane. I haven’t tried completely blocking the rear camera as one poster suggested. While the bikes do obscure the rear view camera you can zoom all the way out and it is usable. I would prefer to be able to keep the tonneau closed to improve range as you do see a drop with the bike rack on already. It would be nice to have a toggle that you could tell FSD to ignore the rear camera but still use the video feed as a mirror.
