This is the kind of stuff that Geoguessr players call "meta" (or "metas").
I personally feel like it's more sporting to learn things like bollards, roadway markings, utility pole styles, and so on, which feel like they're about geography (observable differences in infrastructure or culture that persistently exist in different places), compared to things about Google Maps cars, imagery generations, glitches, redaction patterns, and so on, which feel more like they're about Google Maps itself (historical accidents of how and when the company mapped particular regions).
But if you play a lot or watch streamers talking about this stuff, there will be some kinds of metas that you can't unsee because they may just become obvious to you with time! I felt kind of bad about winning a Geoguessr duel earlier this week because I remembered a glitch meta that I had seen someone talking about on a stream... (you can see it instantly on Geotips if you click on Montenegro!).
Though it is hard to avoid accidentally learning some meta like the Kenya or Ghana cars.
