A collection of humans making a collective decision compromising on everyone’s biases is called politics.

California has decided through a political process to take a step against speeding.

Now, you may not personally like it, but you are in no position to say they are wrong.

Applying Texas’ example as evidence of California’s objective mistakenness is also logically inconsistent. You did not state any conditions which may apply in Texas but not in California. You are equating the two in an all-else-remaining-equal fashion.
