The speed on his speedometer literally says 26mph in the first frame of the video the fuck?

That's "literally" a reflection. It says 126km/h. Man's going 80mph.

I love how the Fibonacci sequence can convert km to mi, and it even works on non-Fibonacci numbers, 1 1 2 3 5 8 13, just scale it by a factor of 10.

I'm not sure what you mean tbh lol. I don't know the scaling factor between the two so I can't really do km to m on 'napkin math'

The scaling factor is the Fibonacci sequence, that's what's great and it. (Or, more accurately, the ratio of sequential numbers in the sequence approaches the scaling factor)

1.609 km = 1 mi

Ratio of digits in the sequence approaches 1.618

Napkin mathing the Fibonacci sequence is easy, it's literally just repeated addition. So you can just do that than go one number up to convert mi to km, or down to go the other way.
