Greater speed differentials leading to collisions is understood to be a fact.
But the risk obviously depends on context.
There are times, places & densities where it's clearly safer to go with the flow and other times when not doing so isn't a big deal. (I'm talking about 10 km/h ... 6 mph ... under, here.)
