It is generally considered bad form to 'explain a joke' but I will break that for you Lucky so you can be 'in on it', despite being the butt.
What Carlin is saying in this joke...
Has nothing to do with driving. Driving is just the example used to highlight a human frailty or trait of 'obliviousness' in a relatable way.
I am sure all of us have been a car with a person who thinks like that when driving.
Despite the fact they may, at times drive above or below the speed limit themselves, they convince themselves that whatever speed they are driving RIGHT NOW is the 'RIGHT' speed not just for them but for everyone else.
Therefore everyone driving faster is wrong and an "idiot" and everyone driving faster is wrong and a "maniac".
He is making fun of people who lack an ability to be self aware and realize that just because SOMETHING makes sense to 'them' ('this is the right speed because I feel it is safe for ME') does not mean it has to be the same for others and they are not WRONG ("idiot", "maniac") just because they differ.
See your post below which has been indicative of the main theme you keep repeating over and over in this thread.

You are arguing that you cannot understand how others disagree because this makes sense to you. You then say they are 'wrong' to hold a differing opinion, on a matter of OPINION, and defend it with 'that should not be controversial because it makes sense to me'.
The Carlin joke would not work if there was not this group of people amongst us that are so oblivious (that is the nicer word btw) that we all quietly laugh at in our daily lives when we witness this trait and think WTF?
It is what is called 'tapping into a common under current'.
So yes, Lucky that person is clearly you. Your question here proves you cannot even read the joke and comprehend it as you are so blinded and lack the self awareness and introspection to see it.
You are literally the butt of his joke. You are why the joke works so well and will endure as a truly great joke.
