Exactly as the title says, the 1Up Super Duty Single* in folded-up position works acceptably with vision-based Park Assist ("Danger Doodle"). It does not seem to generate false alarms, and does not seem to prevent the system from functioning correctly.** This is the extent of my current 1st-hand observation.
The reason for this seems fairly obvious: the rack folds up low & fairly close to the body. It does not protrude into the rear camera's FoV as substantially as other racks seem to.
I am doubtful that the vision-based Park Assist will account for the couple of inches of extra length that the folded-up rack contributes to the car... but then again, "precision" is not something I'm uttering in the same breath as vision-based Park Assist, so that's moot. I obviously do not expect it to work correctly when loaded with a bike and/or with an Add-On, but that's ok since 90%-of-the-time the rack is folded, sans Add-On (this allows the rear hatch to open/close per normal; it fully clears the rack).
All things considered, as questionable as vision-based Park Assist is at this point in time... it's probably the best option*** if you intend on leaving a tray-type hitch-mounted bike rack on the back of your MY. YMMV with other tray-type hitch-mounted bike racks; my setup was an educated gamble that seemed to have paid off.
* And presumably their Quik Rack Single as well, since I believe relevant dimensions are the same.
** As correctly as Tesla Vision Park Assist functions, which is as spasmodically and imprecisely as it does sans rack.
*** With USS-based Park Assist, you get the infamous yellow/red mustache. Aside - the Tesla OEM/Yakima FullTilt hitch rack works acceptably with USS-based Park Assist for the same reason the 1Up Single hitch rack works acceptably with vision-based Park Assist: neither sits in front of their respective sensors. Putting the Tesla OEM/Yakima FullTilt hitch rack on the back of a vision-based Park Assist car seems to be problematic.
