This leads to an overall rise in crime, as traffic stops catch way more than speeders. Criminals tend to break many laws habitually, so it is a wide net. The car bippers tend to speed off (with the famous car flying down a ramp last year as an example).
The whole chain is broken though, Brooke Jenkins as the DA is running into massive issues with SF judges who simply won't prosecute.
Big chance this will end up in another example of anarcho-tyranny. Lots of citizens will pay their fines, but the worst offenders will simple ignore the various letters - and nothing will be enforced.
Let's see.
