You will not eliminate bias as long as humans are involved in the decision making process. So it’s pretty trite to point it out like this.

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.

Ultimately, Gavin Newsom will need to sign it. I doubt he will unless he plans to end this term and move out of California. Remember how Dukakis lost Massachusetts. Different but has similarities.
