What is it about cold blooded animals such as reptiles and amphibians that makes it so that they can’t regulate their own temperature? Doesn’t their metabolism produce heat in the same way that warm blooded animals do?

Why would they want to?
You’re coming at it from the wrong direction.
Endothermic animals aren’t superior to ectothermic ones. They’re just different.
If you lived in a place where the weather was conducive enough, and food was kind of scarce, you’d evolve to be ectothermic too.
It’s a survival strategy. They burn a fraction of the calories which allows them to eat a fraction of the food. In lean times, they’re less susceptible to famines than endotherms, but more susceptible crazy weather.
