Car Speed Limiter

Hi guys, I'm interested in something like car speed limiter "gizmo" and can it be made with Arduino.

I am a newbie at this, I'm just asking questions before jumping to solutions. I don't plan to build this myself, and I don't know that much about cars also. Can someone tell me If this can be done with Arduino, what are the limitations, can it be used on any car engine and stuff like that?

If I wasn't clear, I'm asking if I can limit my car to max speed like 80mph.

Thanks upfront :)

Before you make any modifications to the control system of a car that will be used in a public space get prior WRITTEN approval for the modification from your auto insurers. That includes the experiment an testing phase of the project.
