Just glossing over implementation. So every car will have to have wireless communications of some sort? Will there be some government system that all California cars will have to be integrated with that tracks where they are at all times so the car can know the correct speed limit? A tracking system that surely would never be abused or turned into a surveillance device.
Not unless they think about it for five seconds.
Speed doesn't kill.
It's the sudden stop that kills you.
Be careful, or politicians are gonna draft a bill preventing your from applying too much braking force too quickly. Thats about in line with the logic on this bill.
Next up, skin cancer:
Suns don't kill people. People with suns kill people.
Funny enough, they already did long ago. It's call ABS. :)
Doesn't abs make you stop sooner than both slamming on locking braks or manually pumping them? Idk sounds like more of a sudden stop to me, congress gonna ban ABS next
ABS also shortens your stopping distance. At least good ABS does, originally it sucked.
…or the sudden start.
Lol correct. Speed doesn't kill, acceleration does
Belter slingshot racers know this all too well. NOTE: Spoiler for an episode in the Expanse which everyone should watch if they haven't already.
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.
You realize your car already knows what speed it's driving without GPS, right?
I don't think you're following the implication.
What, that up to date speed databases are an impossible problem to solve? Or that you couldn't possibly get current speed limits from a non-GPS method? These aren't hard problems.
If it's not a hard problem, it wouldn't happen.
You'd be amazed how many problems can be solved when the people involved have legal liability. My first GPS unit was out of date from the moment I bought it. It wasn't because keeping a map up to date was hard, it was because they didn't care, you'd already bought the GPS and it was better than not having one at all. This isn't a technological problem.
Your car's GPS-localized speed map is wrong because no one cares enough to make it right, not because it's an unsolvable problem. It's a gimmick to get you to buy the car, and you already bought the car.
Apple and Google also have problems with speed limits being updated, and they actively attempt to keep their maps updated. Even Waze has incorrect data sometimes, and that can be corrected by anyone. So I don’t think it’s quite as simple as you think it is.
Again, they don't have any liability or financial need to be right. It's a free tool that's better than not using the tool. No one is going to get in trouble if it's wrong, you're not going to buy a competing brand if they're wrong. It's a neat add-on. I don't know why people assume that just because they're a big company they're especially dedicated or competent at managing minor features of free apps. Apple and Google apps are regularly worse than third party developed apps. They're not bad because this is a hard problem, they're bad because they don't care.
And all this "but sometimes they're wrong" is for exceedingly rare errors. 99%+ of roads are right, for the simple fact that permanent speed limit changes are rare. Maybe a database doesn't update for temporary construction speed limits, but in that case we're no worse than we are right now, where your car is perfectly capable of going as fast as you want if you ignore all the posted signs. The only time a limiter impacts driving is when the speed limit goes up, which almost never happens, and simply means people drive a little slower than the maximum while lodging complaints to the repository.
Isn’t the idea that the government would provide an official speed limit database that is updated as soon as a new sign is posted? Seems like a lot of extra work to do it any other way.
Edit: the infra is still exploitable either way, I don’t see how this won’t cause issues.
lol, the government is many things, but quick is not one of them. I’d expect such a database, if ever implemented, to always be lagging behind.
Sure, the car knows its forward speed from its speedometer.
It doesn't know the speed limit of the road it's currently riding on, that's not as easy to directly measure. Currently the most straightforward way to do this is have it look up its location using GPS, use that data to look up what road the car is driving on, and then look up the speed limit for that section of road. This is far from error prone; GPS isn't perfect and could, for example, confuse your current position for another road nearby; it might think you're on a slip road next to the interstate you're driving on, or think you're on rather than under an overpass, that sort of thing. The database might be out of date or in error, the data connection to that database might be unreliable...
The California legislative process: First, say something totally reasonable. "People should be able to tell if the products they buy contain poisonous or carcinogenic chemicals, let's require consumer goods that contain hazardous chemicals to bear a label describing them as such." Next, do absolutely no research, consult no technicians or engineers, only lawyers and yoga instructors get a say. Once you've got all the spelling errors ironed out, have it carved into adamantium so that it's more permanent than god. Finally, strictly enforce the letter of the law in any way it could be interpreted. Which is why literally every single product that might get sold in California up to and including bottles of mineral water all say THIS PRODUCT CONTAINS CHEMICALS KNOWN IN THE STATE OF CALIFORNIA TO CAUSE CANCER on the label, and since literally every manufactured good is labeled as hazardous, consumers have exactly no more information than they used to.
I'm a software engineer with colleagues who work with various localization and short range communication. This is totally technologically feasible. All the "what if it's not sure" cases just default to the higher limit. It won't be sufficient for self-driving cars to know how fast to drive, but it will prevent the vast majority of excessive speeding.
The what-ifs are just people either flailing around to not have their speeding curtailed or people who assume half-assed apps from companies that don't have any reason to care if they're right are the state of the art. They always come up with absurd reasons why they need to speed or why implementation is impossible whenever any road safety improvement is proposed. It's a boring and pathological response.
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.
The infrastructure limitation could be resolved by using infrared reflectors along the road instead of lights. Have the car shine infrared light at the reflectors so it's cameras can read the code on them (like an infrared QR code, maybe?)
Blockage by other vehicles, weather wear, angle from the current lane, it’s fraught with problems.
If we're going to use technically limitations on the vehicle side, we can simply continue to use optical recognition of speed signs instead of changing putting an IR transmitter on every speed sign. It's gotten really good in recent years.
Apart from roads that don’t have speed signs…
Nah don’t worry, they’ll use 2.4Ghz spectrum and drown out WiFi near a road.
We have that already. They are digital license plates. It's voluntary right now fortunately.
Folks… it’s available as a subscriptionnn!!!
I really don't understand why this is a product at all. What value does it provide me for $250/yr?
Saves a few seconds of applying registration stickers every year?
Anti-theft…
Kinda makes sense for fleet vehicles I think, where you’re already installing trackers anyway.
Privacy nightmare for personal vehicles!
I'll buy the argument on a fleet vehicle. But I miss any reasonable use case that justifies the price for Joe Blow the consumer.
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.
I personally can't wait to start hacking cars going by on the freeway to make their top speed a negative value.
That's going to be so much fun.
Similar things have already been done.

Oh yeah, I know.
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. See
or the car use gps, gps is not able to track you(at least not it alane), and you still know where you are
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.
Both of those examples are irrelevant to some of us like myself who participates in neither of those. Those are not good excuses to limit anyone's freedom through legislation.
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.
Not Internet, that's too expensive.
