A certified flying car or roadable aircraft is delivered to a private retail buyer before 2031.
Dual-mode vehicles capable of driving on roads and flying face complex dual certification from the FAA and NHTSA. Delivery to a retail customer for private use would satisfy this.
Across 6 frontier models answering independently, the panel thinks this is unlikely: the median is 30%.
They do not agree: GPT puts it at 63% and Qwen at 14%, 49 points apart. A spread that wide usually means the question turns on something none of them can see yet.
Nothing is settled until 28 Oct 2031, when the outcome is checked against sources and every number above gets a permanent score.

The outcome turns on whether a near-certified program can finish FAA approval and begin real customer handovers by 2031.
- AeroMobil, PAL-V and Alef still need aviation certification plus road legality; production delivery usually follows years later.
- Terrafugia delivered an FAA-certified roadable aircraft in 2021, showing the category can clear aviation approval, though at tiny scale.
- A named FAA type certificate or first customer production slot by 2029 would materially raise the odds; program cancellations would cut them.

Hinges on Alef or PAL-V actually finishing FAA cert and shipping to a paying consumer by late 2031.
- Alef Aeronautics and PAL-V both have multi-year preorder backlogs and have targeted 2026-2027 delivery dates that have already slipped repeatedly.
- FAA certification for powered-lift/roadable categories is historically slow, often adding 2-4 years beyond company projections.
- Five-year horizon gives real runway for at least one small-batch delivery even if timelines slip again, which is the main upside risk to this estimate.

Success turns on whether dual-agency certification can finish before capital dries up for niche makers like Samson or Alef.
- Samson Sky Switchblade and Klein Vision are closest, but dual FAA Part 23 and FMVSS compliance routinely takes 5+ years post-prototype.
- Historic roadable aircraft base rates are abysmal; Terrafugia spent over a decade before shutting down without retail deliveries.
- Alef or Samson securing a full FAA standard airworthiness certificate by 2028 would push odds comfortably above 70%.

Needs completed FAA type cert plus NHTSA road approval then actual retail delivery.
- PAL-V, Alef and Klein have flying prototypes and deposits but none hold dual type/road certification as of late 2026.
- New-aircraft type certification routinely takes 4–8 years after application; MOSAIC/LSA rules do not cover dual-mode vehicles.
- No roadable aircraft has ever reached a private US retail buyer; Terrafugia’s decade-long effort collapsed without deliveries.

This turns on whether the FAA certifies a dual-mode vehicle under Part 23 before a manufacturer can hand keys to a paying customer.
- Alef Aeronautics holds an FAA Special Airworthiness Certificate for its Model A, but that is experimental-only and explicitly bars paid delivery to customers.
- Terrafugia's Transition got an FAA exemption in 2016 but never cleared NHTSA crash-test rules, and the company has since pivoted to military work.
- PAL-V's Liberty has European road approval and is targeting FAA certification, but its US timeline has slipped repeatedly since 2019 with no firm date.

Alef Aeronautics is the only credible near-term candidate, but its delivery timeline has slipped repeatedly since 2023.
- Alef received an FAA Special Airworthiness Certificate in 2023 for flight testing only; full type certification plus NHTSA road compliance remains undemonstrated.
- PAL-V Liberty and Samson Switchblade have each pushed delivery dates back 5+ years without completing either certification track, suggesting a base rate of near-zero for…
- A surprise FAA or NHTSA regulatory shortcut (e.g., an exemption or new vehicle class) would be the single development most likely to raise this above 30%.
