Tesla FSD v14 + Bike Rack Test (Big Change from v13)

[browncowboy]

I wanted to share something I just tested that honestly surprised me.

In FSD v13, running a bike rack (especially with bikes mounted) made Full Self-Driving borderline unusable. The rear camera being occluded caused constant panic behavior; aggressive braking, erratic acceleration, and reactions like something was about to crash into the truck. I stopped using FSD entirely with a rack on.

I recently tested FSD v14 with a rear bike rack and two mountain bikes mounted, fully blocking the rear view; the exact setup that used to break it.

Result:
FSD v14 behaved completely differently. No panic, no wild reactions, and no “bat out of hell” driving. It drove as if it understood the obstruction was intentional. I got the idea after doing a 4,000+ mile road trip, driving through PNW with rain, freezing rain, snow etc. When the camera occluded started to show a warning instead of red hands, I figured that they have improved something. I don't think they are specifically training FSD on bike racks, but the improvement in reasoning, and utilization of front fender cameras (rear facing) is making up for the rear camera occluded image to give the AI enough info to drive normally. However, it still can't do all things, I've documented the results in the video. I also tried to make the video a bit entertaining, will be trying to improve these going forward.

I didn’t expect this to be fixed yet and hadn’t seen anyone else test or report on it, so I documented the full drive here:




I’m a newer content creator focused on Cybertruck ownership, EVs, and real-world autonomy testing — not hype, just practical use cases and edge-case behavior like this.

If this kind of testing is useful to you, I’d love to have you join the community as a free subscriber on YouTube. The support genuinely helps and lets me keep doing deeper tests like this.

Happy to answer questions or run additional tests if folks are curious.

Curious what is the drop in range when you have the bikes on the back?

Good question, I'll test it over a sustained period and report back city and highway numbers.

when I attach my thule outset tent to my hitch, it totally blocks the rear view camera. fsd works just fine for me as long as trailer mode is off

Yeah exactly, you’re on V14 right? V13 it was a different story. Loving the improved capabilities with V14.xx

How did you charge on non-325kw chargers?

Your videos are great, well shot, edited, without to much fluff.

I also noticed the drop in headache with bike racks on the new FSD.

One thing I really worry about with the new version of FSD is the critter avoidance aka emergency breaking for small birds etc. Especially with the inability for the truck to see behind it with a bike rack.

most chargers allow this thing to fit between them. if they dont (and there isnt an occupied pull in spot) its not a problem to detach my tent and put it aside.
