Not the GP but empirically you can't unless you get rid of the majority of FSD's benefit. You'd need to already have both hands on the wheel, have a foot over the pedals, and be paying as much attention as if you were driving - likely more - to see things start to go haywire in that first split second. And, pray that your reaction time is better than whatever FSD is going to try to do.
Maybe that's how you're "supposed" to use FSD but realistically nobody does that. Teslas are not super common in my area but I have one friend who has one with Autopilot and uses it on his ~35 minute highway commute to work. He reads his email on his laptop next to him and doesn't look up at the road until his car gets off the highway. That's how 99% of people will use this.

Yes, more. This is a fundamental problem with these sorts of “computer does safety critical thing but can’t do it perfectly” things; you need someone whose job is to do _nothing_ most of the time, but have full awareness of what the machine is doing and be ready to stop it at a moment’s notice. Humans are, generally, quite _bad_ at doing mostly nothing but remaining super-alert.
I don't understand this "[reading] his email" thing. I can't look away from the road for more than a couple of seconds without the car alerting me to pay attention while FSD is enabled. It's currently both watching for attention (eyes) and nagging on the steering wheel. Autopilot at least does the steering wheel nag every 30-60s. Failing to acknowledge these cause the car to pull over and start blaring alarms in the cabin. I'm not sure how "99% of people" can use it the way you're describing, especially for FSD.
I've personally never felt like I couldn't take control in <1s.
I assume your car is newer. I have a 2018 3 and a 2023 X, and the X will nag me almost instantly if it thinks I'm looking at my phone. The 3 however happily chugs along.
