We've probably all witnessed it at one time or another -- cases of road rage.
But these cases are increasing -- and leading to some big problems on the roadways -- not only here in Arizona, but across the country.
Police say they don't know what's attributing to more people getting in road rage incidents behind the wheel, but a survey done by AAA is pretty startling.
A road rage video on YouTube has gone viral -- viewed thousands of times -- showing a hot headed Marine after a minor traffic incident.
Then there's a California man cutting a driver off, even throwing cans out of his car.
According to AAA, road rage cases are increasing. They looked at data over the past seven years and found there were more than 10,000 road rage incidents which resulted in 12,610 injuries and 218 murders.
Michelle Romanski is someone who knows all too well the dangers of road rage.
"They followed around him and sped in front of the car and started shooting at our car," she said.
Her husband, Miles Romanski, was shot and killed inside his car on January 8, 2012. Police say it was a case of road rage. At the time, Michelle was two months away from having their first baby.
Police say with an increase in these types of incidents, drivers need to be calm behind the wheel.
"If somebody's angry on the roadway, instead of escalating the situation, think about how you can deescalate what will make it go away," said Phoenix Police Sgt. Trent Crump.
The person who killed Miles was never caught -- a thought that haunts Michelle.
"I have to tell our daughter who was born two months after he died that the people that killed her daddy are still out there."
At one point, Peoria police said they had a person of interest in the case. 19-year-old Michael Zamora, but investigators believe he got help from friends and family to flee to Mexico.
If you have any information about Miles' murder, the Peoria police would like to hear from you.
