YouTube's recommendations may be more a reflection of your watch history than a shift in content or a change in the algorithm. I have not seen any van life, off-grid, or tiny home videos on YouTube.
I presume this also removes them as a factor in your recommendations.
You presume too much!

That is helpful to know. I too have run into the errant click problem in YouTube. Drives me nuts.
For one recent example, there was an article about Elon Musk and his girlfriend who releases music as Grimes. I clicked play on one of the embedded music videos and watched about half of it. Ever since then youtube has recommended tons of Grimes videos to me.
I've also noticed that videos my wife or kids watch get recommended to me sometimes.
My work and home gmail accounts get completely different videos because of how I use them. At work it's all background music and albums and at home it's more fun stuff.
