I have an ADHD diagnosis (along with being an aspie, also diagnosed) and I'm never more focused than when I'm behind my stick (or wheel) in my high-ish end and rather elaborate simrig, in either DCS World or iRacing.

So I just looked it up and saw it's considered a risk, so I couldn't get a pilot's licence.

This is so strange; for example I pay much, MUCH more attention to my driving on the real roads than at least 99% of other drivers. In fact I'm always one step ahead, mentally calculating what other drivers are experiencing and how that might make them react - etc. This just happens automatically.

Weird. I guess people are just different, but still.
