Replace the T with a roundabout and reduce the speed limit significantly 200 meters before the roundabout.

Traffic calming measures is how you tackle things like that. Adding a sharpish S-curve to the roads approaching the T should remove enough speed to make it safer. Won't even need a sign.

The counterintuitive thing to do is to make roads "feel" unsafe to make them safe.
A example of this (here done for laugh) is [0], where a single lane muddy curvy hillside road has a speed limit of 80 km/h (50 mph).
The point I would like to make here is that on a street like this is it impossible to joyride and even with low visibility intersections the risk of a T-bone or a fatal crash is minuscule.
This particular example is a strawman of the problem: there are many reasons why most roads cannot be like this, it is just an example of "If the drivers have to pay attention they will pay attention"

Speedbumps are inexpensive and last a very long time.

Sounds like the prudent way of handling your example T-intersection is to rebuild it so it is no longer a T-intersection, or to move it in a way that forces people to slow down (e.g. by turning it 30 degrees, with curves leading into it, or by setting up a roundabout, or by moving it into a position where you see the crossing road more easily).

Perhaps they could install some sort of blinking warning light on top of the hill and maybe joyriding teenagers would heed that warning, or maybe not. Otherwise I think you'd have to cut through the hill or move the roads completely, either of which there probably isn't much money for.
