Not everyone wants an autonomous vehicle 100% of the time.That's simply remote control and would be moving away from autonomous driving instead of toward it.
People drive differently and prefer doing things themselves in certain situations. I'm in FSD beta, and I still have NoA on the freeway set to lane confirmation with turn signal because I can see further ahead than the car can and know it will be faster if I pass a few cars on the right instead of getting behind them too early.
