"That was not the most professional exchange," Jefferson said. "That guy is off-duty in his own personal car, and this guy rides his tail after he pulls out in front of him."
Propper later pulled the driver over down the road, and the exchange began again.
"Give me your license. Someone will be here in 15 minutes," Propper said.
"I had it pinned at 45. I have a camera and a GPS right here, sir. I do," the driver said.
"Give me your license," Propper said. "There is something called aggressive driving, too."
"I wasn't aggressive driving you pulled out in front of me," the driver said.
"You mean to tell me you had to cross a double yellow line to avoid an accident?" Propper said.
"I had to slam on brakes to avoid hitting you," the driver said.
"You are crazy. Tell the judge," Propper said. "You cannot go over a double yellow line. You were not trying to avoid an accident."
"Yes I was," the driver said.
"You where in a hurry," Propper said.
"No I wasn't," the driver said.
"You were in a hurry and all those comments you are making out of there and all that stuff made and all that stuff. That agitates the public. There is no justification. You are not in the punishment business," Propper said.
According to the speedometer on the dash cam, the driver's speed increased after Propper pulled out into his path.
"It appeared to me from what I saw that this individual had enough room to stop his car even though he had the right of way and the person coming from the side is suppose to yield and come out when it's safe," Jefferson said.
The driver was unable to be reached for comment Thursday.
The sheriff and others say Propper was given counseling. Rutherford said it was not discipline but said his behavior was not appropriate.
It's unclear why the driver had a dash cam in his car. There are other examples of bad driving in Jacksonville posted on YouTube. It's something more people are doing, and it's becoming more common overseas as well.
