Jason’s prediction has two parts:
- Time‑bound claim: Within 1–2 years from July 2021 (i.e., by roughly July 2023), commercial space tourism flights would have a lower per‑trip risk of death or serious injury than riding a motorcycle.
- Open‑ended claim: Eventually that risk would fall below that of driving a car.
Only the first part is time‑bounded and testable now; if that is false, the overall prediction fails regardless of the second, open‑ended clause.
Baseline risk for motorcycles and cars
U.S. National Highway Traffic Safety Administration (NHTSA) data show that motorcyclists have a very high fatality rate relative to cars, but the absolute risk per mile is still small:
- In 2023 there were 31.39 motorcyclist fatalities per 100 million vehicle miles traveled, versus 1.13 per 100 million miles for passenger car occupants—about a 28× higher rate for motorcycles.
(nhtsa.gov)
Even if motorcycles are much more dangerous than cars, this still corresponds to a fatality probability on the order of 10⁻⁷–10⁻⁶ per mile. A typical trip of tens of miles yields a per‑trip fatality risk of only a few in a million or less.
Best estimates of human spaceflight / space tourism risk
Historical and contemporary analyses consistently place human spaceflight orders of magnitude riskier than everyday transport:
- As of early 2021, the in‑flight astronaut fatality rate was about 1 death per 31 boardings (~3.2%). (newspaceeconomy.ca)
- A 2023 safety overview notes that about 3% of astronauts have died during spaceflight, and concludes that spaceflight “still is and probably will remain a dangerous industry,” expecting more deaths as tourism scales. (spacegeneration.org)
- For modern orbital crewed flights, NASA‑linked risk assessments during the era of SpaceX Crew Dragon put the probability of a catastrophic failure on a mission like Inspiration4 at roughly 1 in 300 (≈0.3%). (space.com)
- An Aviation Week analysis, using the X‑15 program as an analogue, assumes a ~0.5% per‑flight fatal crash probability (about 1 in 200) for Virgin Galactic–style commercial suborbital flights when projecting program‑level accident odds. (aviationweek.com)
These are engineering or historical risk estimates—not just counting the small number of recent tourist flights. Even the most optimistic of these (≈0.3% per mission) is thousands of times higher than the per‑trip fatality risk for a typical motorcycle ride.
Regulatory posture is consistent with this high‑risk view. For U.S. space tourism, the FAA does not certify vehicles as safe for human passengers; instead it requires informed consent, explicitly telling customers that the vehicle is not safety‑certified and that they fly “entirely at their own risk,” with disclosure of human‑spaceflight accident history and vehicle safety record. (newspaceeconomy.ca)
What actually happened between July 2021 and July 2023?
During this 1–2 year window, Blue Origin, Virgin Galactic, and SpaceX flew multiple paying or privately funded passengers without any passenger deaths or serious publicized injuries. However:
- The overall human‑spaceflight fatality rate and expert risk estimates remained at the levels above (~0.3–3% per mission), far higher than motorcycles.
- In September 2022, Blue Origin’s NS‑23 mission suffered a booster failure; the capsule’s abort system fired and landed safely, but the booster was destroyed. Although this was an uncrewed research flight, the same vehicle family is used for human tourism, and the FAA grounded New Shepard while the failure was investigated. (en.wikipedia.org) This highlighted that catastrophic‑type failures were still a real possibility in exactly the regime being sold to tourists.
So, while the observed number of tourist fatalities between 2021 and 2023 was zero, the best‑estimate underlying probability of a fatal or serious‑injury event per spaceflight remained orders of magnitude higher than the risk per motorcycle trip.
Comparison and verdict
- Motorcycles: per‑mile fatality risk ≈ 3×10⁻⁷, implying per‑trip risks in the few‑in‑a‑million range for typical rides. (nhtsa.gov)
- Cars: roughly 25–30× safer per mile than motorcycles, so per‑trip risk is even lower. (nhtsa.gov)
- Commercial human spaceflight / space tourism (2021–2023): credible estimates in the 0.3–3% per‑mission range, i.e. one chance in hundreds to low dozens, far higher than road transport.
Given these orders of magnitude, there is no plausible basis on which, by July 2023, commercial space tourism had genuinely become safer per trip than riding a motorcycle, let alone safer than driving a car. Regulatory treatment and expert commentary in this period explicitly describe space tourism as a significantly higher‑risk activity than common transport modes.
Because the time‑bounded part of Jason’s prediction (“in the next year or two”) clearly did not come true, the prediction as a whole is best classified as wrong, even though the longer‑term “eventually safer than cars” clause remains untestable at this time.
