we all assume that we know whats really going on
the mind set of officer(this is his job)
the incident(there may or may not have been a need to get over to the #1 lane for a critical call(maybe a scooterist down in the 1 or 2 or 3 lane up ahead)
i have watched it enough to get over the knee jerk reaction period and he was doing what he needed to(the intent is clear)
safe or not safe is observational at best
he is a skilled biker and that was his call
now to add to the suggestion box, if doable, would have been what is called a rolling traffic block
you enter many exits prior and begin a controlled traffic blockeventually halting all moving vehicles
this can be done in a matter of an 1/8th of a mile
so if there was an on ramp prior to that one he or she would enter weaving and slowing the entire flow of traffic up to the incoming emergency vehicles
(what really should have occured is the truck driver should have come to a complete stop regardless)imo
