Ahead of the curve

[totient]

Someone shared the viral "superman" bike descending video with me, which made me go look for an example of the one-armed supertuck I was fond of back when I was racing in the 1980s. I couldn't find one, nor much evidence of supertucks' existence then, though I did eventually find a text description of someone doing something like it during the Race Across America at about that time.

Then I went and read my feed and, speaking of the 1980s, discovered that I had also anticipated yesterday's XKCD by about 35 years.

In neither case was this a particularly good idea.
