I have an idea. What about putting a solar powered radar that lights up a flashing sign when cross traffic is detected to draw the driver's attention. Even better would be coupled with signalling that indicates which direction a vehicle is approaching from. Even more advanced would be to compare the vehicle speeds from both roads, and change the warning from yellow to red flashing lights if a collision is immanent. Actually, I'd like to see that last part put into place at any hazardous intersection, in case a driver misses seeing a stop sign or red light.

This is in the Tom Scott video, but in the case of this intersection there is a combination of conservation area limitations, light-pollution concerns, and a complete lack of electricity.

Generally one would prefer safety features to be fail-safe, not fail-deadly, i.e. traffic lights that give you green when there is no cross-traffic is OK, but warning only if something is detected is used only in limited circumstances.
