People don't drive, generally, at drastically different speeds and ways.
People that know full CFOP can average 50 seconds, while faz may average 7.5 seconds.
None of my five definitions involve people knowing full CFOP and averaging 50 seconds (well, maybe the third, but very unlikely). The fourth doesn't even use people at all, and the fifth only rather indirectly.
Sure, you can make up bad measurements. But that doesn't mean good measurements are impossible. I believe all the people and programs I actually did use in my definitions are pretty good and the variation between them isn't like 50 to 7.5 seconds.
Also, yes, there's probably not a factor of 6.67 in variation of travel speed among different drivers actually driving at similar times at similar points on the route. But factor 2 to 3, I believe. And what what about traffic jams? That can influence times quite a bit. Also, the routes I showed are said to take 41 and 42 hours, respectively. Pretty much nobody is going to drive non-stop. During that travel, people will usually have to take breaks for various reasons, and their number and durations differ. And some noob drivers might be bad at reading maps and take much longer cause they're constantly uncertain where to go or even get lost.
But even if the driving variation were smaller, I'd say that would just make the route times more accurate and reliable. Not turn them from impossible to possible.
This is why routes can have speeds - people drive somewhat similarly.
This is why methods can have speeds - good cubers cube somewhat similarly.
