I'd say "unsurprising" rather than "under control", but yeah, I think that's a big part of it. If it's slow, you have time to see and anticipate what's going on

I'd say "unsurprising" rather than "under control", but yeah, I think that's a big part of it. If it's slow, you have time to see and anticipate what's going on, even if you don't control it. It's the same with humans, really -- you feel better and safer around someone that has calm and slow movements than around someone that nervously jerks around all the time.
