No you don't need a second profile for that, you can just pull down once on the right stalk to enable regular adaptive CC with lane keep instead of twice for FSD. This second profile requirement is complete nonsense.
The "pull once for FSD" that removes the regular adaptive CC is a voluntary option in the settings, you can just disable that. If you have that enabled and don't like it, that's your fault not theirs.
I just find misinformation really annoying. Like, There's loads of reasons to hate on Tesla and Elon Musk, there is no need to make up stuff that isn't true, it just takes away from the actual lies and issues and drown out valid criticism.
