This won't pass. It's legal to go any speed you want on private property you own; a challenge at the CA Supreme Court would likely eviscerate any bill like this that were to pass. Enforcing speed limits isn't a trivial problem. It only seems like one if you understand it from the very limited perspective of merely knowing the limit (kinda) at any time; once you start enforcing that limit, you create liability and danger where previously there was none. What about speeding to the emergency room? What about an open road on your own property within California's borders? What about a racetrack? There's just no amount of current infrastructure which can model this properly and without enormous holes, some of which would immediately conflict with rights most Americans consider sacrosanct.
