I notice it when traffic lights change. I think high IQ people prefer to drive. That radar that is being put in autos to sense accidents ahead of time - our brains do that. Also, we are more likely to be hurt in an accident because we see it coming, tense up, then get hit and it can make our soft tissue injuries worse. I have it logged for any future such situation, if you can't get out of the way, don't tense up.
