It was already discussed in your now-locked thread that the only locations where the speed limit drops from 70 to 55 (excluding tunnels & toll plaza approaches) is the stretch east of the Allegheny Mountain Tunnel & the stretch east of Bensalem. I don't see any curve advisory speeds on the stretch east of the Allegheny Mountain Tunnel (meaning 55 is appropriate for those curves), and from a quick GSV sampling 55-60 seems to be the typical curve advisory speed elsewhere.
If you're going to keep beating this dead horse, at least do it in your containment thread & stop polluting legitimate threads with this car-flipping nonsense.

"LOS"? "DHV"?

These are traffic engineering terms.
LOS is Level of Service, generally graded from "A" in the free-flowing condition to "F" in the constant traffic jam/demand>capacity scenario.
DHV is the Design Hourly Volume, as defined above.

Or people could just actually drive for the conditions and not have to worry about "flipping their cars over." If someone is that reckless then perhaps they shouldn't be on the road.

But most of those curves can't even handle the speed limit.

That's not unusual. That's why God invented advisory speeds.
