FedEx Road Rage against another innocent truck driver.

Dangerous FedEx Ground driver shows how to almost kill people and crash trucks. No idea why, but I think he should have his CDL revoked before he kills someone. FYI, first audio was driver talking on CB radio to more or less let folks know what was happening.
Note: The driver tried to talk on the CB radio to the FedEx driver without response. Likely the FedEx driver had no CB radio.
PS: FedEx was contacted over a period of weeks because nobody could figure out what the persons home terminal was for a while. Finally the home terminal was informed. FedEx did nothing about it of course...
Update: All vehicles had just come through a single lane 35MPH construction zone. The speed limit at the time was 65MPH which the driver was doing. The white truck never got far enough ahead of the red truck to safely pass. The driver followed the truck to the off-ramp because he was waiting for responses from police. Sooo, driving the speed limit in the fast lane is a no-no to many drivers, but the only way this driver could get back to the right lane safely was wait for an opening or slow down a lot and hopefully move over.
