I also do that, but without really having any expertise besides interest in the subject, I'd say this is different from intrusive thoughts. Intrusive thoughts are not voluntary things, they seem to come randomly and by accident, so to say. You say that all these things you think just come to your head also, but like in my case, I'd think they are consequences of a certain mindset. In my case I would even dare say this is how I've been raised. I see the benefits of observing these details, of having a plan, not only in my day job (I'm a software engineer, and probably most people here would agree that it's very useful to be able to easily go into "what if..."), but also in daily life, i.e. I'm on a hike, what could go wrong? or a better example: I'm one of the Fire Wardens in my office. Believe me, I've run plenty and plenty of scenarios for that in just an attempt to be more prepared for situations that could actually happen at some point. So when you care about these things, you have awareness for them... I guess you end up thinking about them just as business as usual.
