[Water Warrior 2]

This is truly a sad situation. 5 dead and others injured due to what is probably an impatient driver. I am assuming this was on a 2 lane road with limited passing zones. Limited passing zones don't give anyone the right to take chances and endanger other road users. Whether or not the bikes were a little above, below or at the speed limit is not the point. Not everyone travels at the same speed. The only constant is the maximun allowable posted speed limit and that only applies to ideal conditions.
The fact that the Honda driver left the scene does not imply he/she is a great driver or reponsible citizen. That person will be found and will have a lot of explaining to do to the authorities.
Things like this sometimes make me wonder why I still ride.
