Thinking the same thing. I say hold in your lane, go the speed limit, and let the idiots do what they do. Slow if necessary to keep a safe distance with the biker in front of you. Do not swerve to avoid a crash - hold your line.
Good advice.
That’s what we’ve had to do several times even though *we* were on bikes, too.
Just let ‘em go and watch out for possible flying debris.
