The guy in the truck is an asshat
The person video taping was breaking the law on two accounts.
Video taping while driving and
316.081 Driving on right side of roadway; exceptions.—
(1) Upon all roadways of sufficient width, a vehicle shall be driven upon the right half of the roadway, except as follows:
(a) When overtaking and passing another vehicle proceeding in the same direction under the rules governing such movement;
The video taping driver wasn't overtaking or passing anyone for the first 45 seconds of the video. What's worse is that the driver seems to have been driving parallel with a larger truck on the right. The driver with the video should have passed the larger truck and the white truck on the right and then gotten in the right lane around the 2 second mark of the video. Or they could have slowed down and gotten behind the two vehicles on the right.
The video taping driver instigated this incident.
And showing the odometer doesn't make things better. Regardless of what speed you are driving, you should ONLY use the left lane as a passing lane.
IF you are not actively passing another vehicle, you are breaking the law.
you should never use the left lane as a cruising lane
