Different levels of autism?

The 'severity' of autism in the individual is very often context-based. If you saw me giving a seminar on something I know a lot about, you would think that I was amazingly functional. Put me in a crowded area, however, where I could not escape, and where loud noises happened at random intervals and I would very soon be rendered entirely unfunctional,

I completely identify with this statement..

I am in complete disbelief at much the risk of harm increases in overloading situations, because I could’ve been complete aware of my surroundings moments before, then on go the sensory-blinders..

In crowds a get angry, whilst driving I get sleepy, when I can’t see I can’t hear either..

No i’ve never been cornered like that, but I feel it in my neck and it forces my head down and hands become rigid, and then I just think psychotic thoughts until something distracts me. 
Actually now that I think of it I have lashed out a few times, but never at strangers in public, but I would chalk it up loss-of-control, because when the trigger is finished I am finished..

Having said that, I think that if I was drunk I would have significantly less control, I am less controlled in general when I drink..
