Does tinting windows really reduce the temperature inside the car?

I'm looking into ways to keep the heat out of the car and window tint is the option that shows up most often. I took a moment to think about it and here's what I got:

A reflective coating on the window would physically reduce the amount of light/heat entering the glass, but not so with normal window tint. The darker color absorbs more light/heat than normal glass, so less makes its way directly into the car. But where does that energy go? It gets radiated as heat on both sides of the glass, in particular into the car.

So what am I getting wrong?
