Maybe not, but perhaps a 20MPH speed limit will result in vehicles going
35MPH, while a 35MPH results in vehicles going 50MPH.

Thus speaks the Mayor... Which says something about law enforcement in
California.

I am being a bit cynical here as actually law enforcement in a
democratic society is more a factor of what the voters actually want,
or will accept.

It's a trade-off of enforcement versus how much voters are willing to
pay in taxes for more police, more courts, more jails, and more prisons.

There are many laws that are simply not enforced but that most people
obey anyway. Should I ask the sheriff to start enforcing the lack of
front license plates on many cars simply because it's illegal not to
have one? Or should the time of each deputy, that costs us hundreds of
thousands of dollars per year, be used to address home and car break-ins?

Spending on traffic calming infrastructure that prevents the most
egregious and dangerous actions by vehicles is mostly a one-time expense
other than some small additional maintenance costs. Speed tables,
sharrows, protected bike lanes, curb extensions, chicanes, bollards,
etc. can all be used.
