The passage around this formula
The arithmetic behind that result is worth making explicit, because it explains why the next eighteen months mattered more than the raw distance suggests. If a course of length L miles must be driven without a mission-ending error, and a vehicle’s probability of such an error is q per mile and roughly independent from one mile to the next, the probability of finishing the course is approximately . Over a 142-mile course, even a per-mile reliability of 99 percent yields a finishing probability under 25 percent, and the 2004 fleet did not come close to that bar. This is illustrative arithmetic rather than a number drawn from any cited study, but it frames what changed by…
