Road rage means driving in a rage, changing lanes randomly, overtaking another car, etc, a kind of mental illness called intermittent, fulminant disorder (IED)  studies have found that the proportion of IED patients who test positive for Toxoplasma gondii is twice that of the non-IED group
Mice infected with Toxoplasma gondii tend to be bolder, more adventurous, and therefore more likely to be caught by cats
 Researchers believe that Toxoplasma gondii infection may be the culprit leading to IED including road rage
