I have Bookface friends who are truckers, and this California law has them freaking out. It would freeze out a huge section of the public, for an issue that has a million Federal hooks in it. It's difficult to imagine a law that's a less-clear example of violating "Interstate Commerce."
As I mentioned in the OP, the target of the law - I do mean
target - was outfits like Uber and Lyft, who screwed up major cities' taxi medallion oligopoly-racket. But because the law couldn't target the companies by name or business plan, it was written broadly, and folks as varied as indie truckers and free-lance writers got ensnared. I suppose it's a case of the Law of Unintended Consequences, but the Sacto-Idiots are so hostile to business that I wonder about the "Unintended" part.
