Not a regular watcher, but I have watched and enjoyed many of her videos; great content, and clearly from someone very knowledgeable and passionate about cars - cool with me, and I'll continue to watch.
That said, the only reason I came across her content was because I heard about the trans thing and looked up the channel to see what the deal was. I am sure I am not the only one who did the same, so let's not pretend it isn't a factor in her popularity.
