While not ideal, this can still be useful. In Sweden, we employ speed cameras strategically around areas of higher risk, such as intersections with cars coming onto a larger road with an obscured view. Reducing the speed in that particular spot does probably save lives.
Still, adjusting the design speed is the preferable alternative, but that does not make speed cameras completely ineffective.

Up until ETOPS (aka Engines Turn Or Passengers Swim) was introduced in 1986, it was not even legal to run cross-atlantic flights to and from the U.S with twin engines.
As I understand it, point-to-point taking over from hub-and-spoke coincided with mid-size high-range airplanes like the 787. Before that, the economics of running point-to-point had trouble penciling out, since you needed fairly large aircraft to handle the distance. Hence, hub-and-spoke made sense - run small aircraft to and from hubs and then run a large long-range aircraft carrying a large amount of passengers.
