see what's hapenning instead of being the reason it happen
Answer:

No better advice is needed!
If you expect the unexpected to happen, and it doesn't, you're relieved. If the worst does happen, you're most likely prepared for it!
example............
You're goin' down the road @ 60 mph in the right lane. You see some dipshit (in your mirror), haulin azz in the far left lane. There's about a 95% chance he's gonna do a 'Hail Mary Get-off' by slamming on the brakes and doing a hard right...........right in front of you!
BEWARE!!! Dumbasses like that clown CAN & WILL ruin your driving career if you hit him!!!
Pay attention to what's happening around you at ALL TIMES!!!

Answer:

And this is news and a surprise to you why? It is only common sense, what with school being out and the vacation period starting up. Still haven't figured this one out after "20 years"?

Unless the debris was feathers or pigeons... YOU were following too close if it was still flying by the time you came up on it. You did say flying debris.
One would be well advised to stay well back of your rig... to avoid all those placards "flying" off.

That is incomplete advice.
1) Move left if emergency vehicles and/or police on the shoulder. In some areas you can be fined for failing to do so if the way on the left was clear to move over and/or you made no effort to find a clear spot.
2) Move left for any sort of vehicle or obstruction on the shoulder. You never know what may dart out from around it or perhaps the object itself dart out onto the highway.
3) Only move left if the way on the left is clear. A driver can perhaps make their own opportunities well in advance by scanning as far down the road as one can and their mirrors.
4) No sudden last minute moves left. Smooth as she goes.
