Also, when we are driving, we're in a pretty high state of anxiety; just as a baseline.

I find it amazing, that, when I'm driving, and some knucklehead does something that almost makes me crash (and thus, maybe kill me), I get incandescent with rage, but, five minutes later, I've all but forgotten the incident.

I could easily see myself fanning that rage into something that could result in self-destructive road rage.
