If I use a private window, and don’t log in I get a lot of right-wing stuff. I’ve noticed it probably depends on IP/location as well. If at work, youtube seems recommend me things other people at the office listen to.
If I’m logged in, I only get occasional right-wing recommendations interspersed with the left-wing stuff I typically like. About 1/20 videos are right-wing.
YouTube Shorts is different. It’s almost all thirst-traps and right-wing, hustle culture stuff for me.
It could also be because a lot of the people who watch the same videos you do tend to also watch right-wing stuff.
In general, the algorithm tries to boost the stuff that maximizes “engagement,” which is usually outrage-type stuff.
Linus Tech Tips reviewed one that came with a little radio tower it used for position (guessing it used a combination of many sensors). Seemed to work OK in his flat little backyard.
