Speed doesn't kill.

It's the sudden stop that kills you.

One of our cars uses GPS and a lookup to show the current speed limit on the dash. It's often wrong. This will not go well.

One way I could think to implement it without any tracking or data connection connection with no data being transmitted from the vehicle would be by placing infrared strobe lights periodically along the road, possibly at the same places we already have speed limit signs. The flashing is invisible to the human eye but could be picked up by cameras on the vehicle, vary the speed or pattern of the strobe to indicate a different speed limit.

Something pretty similar is already used by a lot of emergency vehicles to trigger green lights, just the arrangement is reversed with a strobe on the vehicle and a sensor on the traffic signal.

Of course such a system would potentially be vulnerable to things like power outages (strobe can't strobe if it doesn't have power) bad weather (heavy fog, or if the camera and/orr strobe are covered in snow,) and someone could potentially circumvent it by just mounting a strobe light on their car pointed at the camera.

You could probably address the snow/fog issue by locking the car to a lower speed if no strobe is detected, maybe 25 or 35mph, because in those conditions people should generally be driving slower anyway, and then you don't have the expense of needing to put strobes around lower speed areas. And the power issue could be addressed with the kind of solar panels and/or backup batteries that already power some streetlights and such.

And for those who tamper with the system to circumvent it, we're never going to stop speeders entirely, but we can increase the fines to make up for lost revenue to keep police departments happy, they make less traffic stops and rake in the same amount of money.

Will there be some government system that all California cars will have to be integrated with that tracks where they are at all times

We have that already. They are digital license plates. It's voluntary right now fortunately.

I haven’t read the article, so just spitballing here: I have to assume the approach here is to electronically govern the engine to go no faster than the highest speed limit. I don’t know what the limits are in California, but where I live that’d mean the car would be limited to 80mph. If it was electronic, it could be adjusted if then limits were changed.

Otherwise, it’d be insane, and require the crazy infrastructure you describe. And they simply don’t have the money or the wherewithal to build an actual coverage that would allow the limiter to dynamically scale all the time.

Alternatively, I suppose you could imagine a hybrid system—ie an overall limited engine to the max limit, and then some sort of transponder that would throttle the limit down if you were near an important speed limit zone, like a school, which they could manage to deploy a transmitter at… still seems technologically challenging for the state to really pull off consistently though.

Either way, yeah not a fan or including more required tracking tech in vehicles. I don’t think I’d really hate a reasonably limited car—I really can’t justify needing to drive over 80 ever really, even in an emergency, but it would drive me insane to have the car just magically throttling down whenever it thought it was time to.

Every car I've hired in the last ten years has the current speed limit displayed on the dashboard. It does not require the car to communicate any information, only to receive it.

That is a different question from how car manufacturers could abuse the requirement to get more data to sell, of course. But there's nothing in this bill that would require the car to collect any data that isn't already publicly displayed by the roadside.

or the car use gps, gps is not able to track you(at least not it alane), and you still know where you are

There is already a good amount of wireless in most cars. We've had standards since the Bush administration for cars to wirelessly communicate with each other.

So Uber already does this. Yes, you need to have GPS enabled, but Uber can tell when you're speeding. Same with insurance companies and their apps. The technology to determine what street you're on, what the limit is, and how fast you're going already exists.

Not Internet, that's too expensive.
