Typically I'm a calm, cooperative driver. There is one situation though that I admit can raise my blood pressure. If there is a lot of traffic on the highway and progress is slow, that doesn't bother me at all, as there is nothing I can gain by getting passed the car in front of me; there is just another one in front of him and so on. But when the car in front of me is driving slowly and can readily move over to the right, but will not, and there is nothing but daylight in front of him, I quickly get annoyed. That promise of better progress on my trip, being blocked by one (what I consider to be) inconsiderate driver, really gets my goat. And there is nothing I can do about it but wait...
What is this new technology that can identify this emotion?
