That's not how speed limits work. They are legally required to be raised if traffic is going faster:
"Once the road is built, engineers will evaluate the existing speeds by measuring the operating speed. They often do this by measuring the speed that 85 percent of drivers are travelling at or below, called 85th percentile speed."
Tell me 1 instance of a freeway that raised speed in recent years. Practically every freeway in CA that's not the 5 has a 65 mph limit. Traffic absolutely doesn't flow at that speed on a bunch of them.
