Motorcyclists: If you are riding this fast on a public road, you cannot expect other road users, especially those driving semis, to see you coming. Never mind what happens if you make a mistake. I was doing between 65-70mph, so I’ll let you make your own guesses as to how fast this dude was going.
I completely agree that car and truck drivers in general need to be more conscious and courteous to motorcycles and bicyclists on the road, and vice versa (and of course plenty already are). However, my personal opinion is simple: I cannot be made to care more about your safety that you do.
