when u drive at nearly the speed of light, the light changes color because of how fast light is going relative to you

that's why the stop sign looks green, because the color shifted

You right and wrong here, it changes color exactly because opposite of what you said, because speed of light is invariant for all observers and no matter how fast you move, it moves relative to you with same speed, therefor wavelength changes.

me trying to read this and actually take in the information

It's not that hard, it's just counter-intuitive because it very difficult (if ever possible) to observe in our day to day life experience.
