I can see reading comprehension isn't your strong suit so I won't try to debate with you further but just to re-state what I said:

So it's 60 feet then it's 30m... Hogwash.
So you want to quibble about the difference between 98 feet 5 inches and 100 feet? Research into binocular vision has shown that not everybody has the same capabilities, so not everybody's binocular vision is effective to that distance, as I said.

That only works to maybe about 60 feet away for a person with typical vision, and at most 100 feet for someone with exceptional vision
It should be obvious that if it's a bicycle, it's not unidentified. You've identified it as a bicycle. You really should read more carefully.
The only way you can determine the distance and speed of an object in the distance with no further reference is if it's an identified, known object.
If the object is unidentified, it's not possible to make such a determination of the distance and speed.

Regarding your bicycle question, you're having more reading comprehension and or memory difficulties. What I said before was
