40-50. Until I look down and realize I'm splitting at 70. Funny how traffic slowly starts to speed up without me realizing it 
[there] are times when 2-3 cars like to hold hands and go at 65mph across all three lanes without separation, then i'll split just to get past the moving roadblock.
Above 40-50 mph I change from splitting to passing.

I will split at any speed as long as my delta is within ten mph of others vehicles.
Ding. Ding. Ding.
I didn't vote...To me it isn't a speed number issue, it is a situation issue, and that varies widely and wildly.

...Regards of speed if two objects are moving together within 10mph of each other the danger is low. The speed that both objects are moving at doesn't matter because the reaction time will still be the same at 300mph or 20mph between the two objects...
Being a student of human behavior, this phenomenon is a mystery. What goes on in those four drivers' minds? Entitlement, oblivion, negligence, carelessness, ignorance?...sit behind a rolling road block on a 4 lane interstate with nothing in sight for a mile.
Your physics seems precise. For a small mistake in the reaction, there is also something called impact (with the asphalt) which I think is going to be a little different b/w 300 mph and 20 mph.
Very true however we are talking about controlling a motorcycle and not what speed is it safe to crash at. If that was the case then we wouldn't go over walking speed because people die from falling and hitting their heads.
I posted on my iphone earlier and really couldn't get in a good paragraph on why I do this.

The blue angels are a great example of what can be done at crazy speeds safely and so are motorcycle racers.

Really - the available reaction time is the same whether you're racing/flying along side someone (going about the same speed) at 300 mph or 20 mph?![]()

Whereas Entoptic certainly meant that relatively speaking regardless of speed the delta is always the same, however, there are different rules and forces at play at different speeds. Down force, air friction, noise, stability, etc. It's increasingly more difficult to smoothly swerve a bike at 100mph than at 50mph.Really - the available reaction time is the same whether you're racing/flying along side someone (going about the same speed) at 300 mph or 20 mph?![]()
One for Mythbusters.The distance traveled during the reaction time would obviously be farther at 300mph than 30mph, but reaction times would be identical.
