I feel like if you sample your vertical angle frequently enough you can always catch it.
Let me try the r/ELI5 method.
lets use the human body as an example on a flat stable surface (floor, ground, whatever)
If you get on your hands and knees you can crawl, you can stay stil, you can lean forwards/backwards, and side/side but still be stable. Gravity will hold you in place. No surprises. This is analogous to a car with 4 wheels.
If you stand up you have less stability but more mobility. You can bend at the ankles, the knees, the waist. If you lean over too far you fall over. Gravity is still pulling you down, no surprises. This is analogous to a motorcycle. The key is to not lean over more than you need to.
If you stand on top of a narrow stool or step ladder, on the very top its a tiny flat surface. If you lean over a bit you are OK, if you lean over too far you fall off and hit the ground much harder than the above example. This is analogous to a helicopter or slow plane (tilt too far without forward speed in relation to your control surfaces and you fall out of the sky). The key is to not lean over more than you need to.
If you stand on top of a flag pole you are very unstable, it's not even a flat surface. You might be able to lean slightly without falling off but definitely less than you could lean in the above examples. This is analogous to a cargo rocket. You don't want to lean at all. You can turn with thrust at a 1 or 2 degree angle but you can't do the looping swooping changes a helicopter or plane can do. If you fall over you go boom.
Say remember when I talked about the autopilot / flight computer on the rocket. Well it knows when it's tilted to far and will blow itself up if it can't correct the situation. That's how automated it is. It'll take one for the team if it has to.
I don't say this lightly. People, many people have lost their lives just trying to keep these things pointed upwards and moving straight. It's not an easy field and I have a hard time giving that sort of gravitas to talking about autopilot for a car. You can walk away form just about any Tesla crash.
