For a drunk guy, he actually drove pretty good. Granted, he crossed the center line more times than I could remember, but considering his speed and high center of gravity, he did quite well.
Moving on to the reckless driving/ reckless endangerment... yes, he absolutely should be charged with both crimes. Attempting to run a motorcycle off the road is basically attempted murder and I hope the judge throws the book at that truck driver.
From a LEO perspective, those motorcyclists should have NEVER stopped. They had video evidence and could have walked into the County Sheriff's Department and made a complaint. Confronting a driver these days as a civilian is risky, and not a good idea.
I'm glad nobody go hurt because this guy could have killed lots of people that day. I remember at least once when the truck driver was either on, or slightly over the double yellow line as oncoming motorcycles approached in a curve while leaned over. That could have been really bad.
