I believe you're referring to Braess' Paradox, right? This was a very surprising effect for me to learn about, just recently Veritasium covered it in their video on a mechanism that becomes "shorter when you pull on it": https://www.youtube.com/watch?v=-QTkPfq7w1A
Yes, I saw the same video! Having played Cities: Skylines, it was not that much of a surprise, more of a neat formal explanation.
