If I wrote down words on paper that you had to give fellatio to anyone who demanded, would you do it? What if I got all your neighbors to agree that you should give fellatio to anyone who demanded it? What if I got all your neighbors to agree that you should give fellatio to anyone who demanded, or be shot?
I would choose not to reside in such a community. There are a variety of communities with a variety of speed limits. Find a community with a speed limit you can accept and live there, or work within your community to change the local speed limit law. But if you choose to live in the community, you choose to be held to the laws that community has put in place. Additionally, forcing me to commit such an act does not protect others from harm, and arguable could be considered as causing harm to me. This would be the opposite of the laws being discussed where forcing a me to drive at a safe speed decreases the risk of harm to others and myself. Nobody said anything about shooting speeders.
Following rules because they are the rules is no different from following orders because they are orders.
True, but failing to follow orders has consequences as well. You can choose to refuse orders, but in doing so you choose to have those consequences imposed upon you.
"I am free, no matter what rules surround me. If I find them tolerable, I tolerate them; if I find them too obnoxious, I break them. I am free because I know that I alone am morally responsible for everything I do."
Robert A. Heinlein
Heinlein was a fiction writer. He said a lot of stuff, most of it fictional. That doesn't make him someone whose words I would choose to live by.
