Look I'm as much "fuck cars" as the next guy but riding a motorcycle on a highway is unironically suicidal. I personally know a guy who got in a bad crash on one but miraculously survived; he had a year long recovery period but will have various pain and dysfunction in his body for the rest of his life. I also know some people who did pathology rotations (state medical examiner office, autopsy basically) and the big three categories of bodies coming in were drug overdoses, suicides, and motorcycle crashes.
One of the facebook comments links to a seventh person who died a few days before these on June 18th: https://www.fox13seattle.com/news/motorcyclist-killed-sr-530-crash.amp
Honestly as a cyclist in an area with poor cycling infrastructure, I would feel a lot more comfortable riding a motorcycle than I do on my ebike, highways excluded. Riding in traffic is much safer than riding alongside traffic, you are far more visible and that's the single most important aspect of road safety.
I agree, I used to cycle all over the place on the road and I wouldn't do that any more. Motorcycle gear + moving at the speed of traffic is far safer than spandex, a foam brain bucket, and differential speeds up to 40-50MPH
