What is the reasoning for NOT having a "low coolant" light in many cars?

I drive a popular Japanese car from the previous decade, and am always in the habit of checking coolant levels since I appear to have a slow leak. Apparently this car does not have a "low coolant" light (like all cars, it has an engine temperature gauge/warning), and plugging in "low coolant light..." in Google will autofill with American and European cars, but no Japanese models. Of course, we can speculate about certain cars' reliability leading more people to Google them, but what's the reasoning behind many cars not having coolant warning lights?
