ADHD adults and a control group were evaluated with a virtual driving simulator. The simulator gave subjects a high-stimulus driving situation and a low-stimulus driving situation, with two periods of monotony. The study found that adults with ADHD were more likely than controls to have a collision with an obstacle during a driving simulation. They were specifically more likely to have a collision in a monotonous low-stimulus environment.

This means that if you have ADHD and your drive is boring, your inattention kicks in, and you are more likely to have a collision if something runs out into the road.

One part of the driving simulation involved having to avoid a collision with a virtual dog. I think I would need therapy after that one.
