No, no - I didn't mean to imply anything about safety or whether or not they went with the flow of traffic or not.
I just like the speed figures included with events like this so the general public (at whom the event was aimed) has some context for understanding the results. (In other words, so they don't get mad when they only get 30 mpg in their Fusion hybrid going 80 mph down the interstate.
)
The context you give is just the kind of info we need to get a better picture of what happened.
