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.

"I don't think it's at all an overreach, and I don't think most people would view it as an overreach, we have speed limits, I think most people support speed limits because people know that speed kills," Wiener said.

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.

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.

I am not a "muh freedom" guy, I don't drive more than 10 over anyway. But this is just logistically a bad way to stop speeding.

Where does my car get the current speed limit information? How and when does it update as speed limits change? Will school systems around the country have to submit a list of which days are "school days" for school zone speed limits?

What if the GPS registers you on the 30mph road below or next to the 70mph highway, long term or even for a momentary glitch? Who is at fault if that causes you to be in an accident?

Will school systems around the country have to submit a list of which days are “school days” for school zone speed limits?

Story time!

There is an elementary school a few towns over from me which happens to straddle the only viable throughfare in that area. Note that this is out in the country, so it's not like it's on Main Street or anything. There is no other road. Well, it's got one of those blinker signs that says "15 MPH speed limit when flashing." It's meant to be used during pick-up and drop-off times, for obvious reasons.

A few years ago some cantankerous asshole at the school with no real authority decided that people were "zOoMiNg ToO FaSt!!!!" on "their" road and during summer vacation flipped the sign on and left it blinking all day and night. Then a bunch of "anonymous" calls starting coming in to the local PD about people exceeding the 15 MPH speed limit. They had to get somebody with keys to come out and turn the fucking sign off. And the next morning, lo and behold the sign was once again mysteriously turned on. This process repeated for several weeks until the culprit was finally caught, who unsurprisingly was some low-grade administrator for the local school district. Insofar as I am aware no actual punishment was meted out.

Tl;dr: If you give petty egos even a tiny amount of perceived control over people's lives they absolutely will abuse it to the fullest extent they are physically or technically able to, without fail. It's not a matter of if, it's only a matter of when.

[–] Veedem@lemmy.world 51 points 9 months ago (4 children)

What about in an emergency? What is someone needs to go over that limit for evasive maneuvers or something?

I get it, people speed, but put the cameras up and just fine them. That’s all.

I saw a video yesterday of cars fleeing the 2011 tsunami in Japan, I'm willing to bet those people exceeded 10mph over the posted speed limit trying to get away from the water.
Limiting the speed of the vehicles isn't going to improve driving skills or eliminate distractions. It isn't going to make people drive safer, just slower. I'm sure any situation where people need to go 10+ miles over the speed limit is going to be exceedingly rare and limited to things like fleeing forest fires or tsunamis, but limiting the speed isn't going to have a huge impact on accidents.
It could decrease fuel consumption and emissions though 🤷‍♂️.
But it still seems like a problem that could be solved with better enforcement.

There are reasons other than natural disasters that happen all the time. Health emergencies are a fine example of this. Yes, ideally you’d wait for an ambulance but oft times that’s just not viable.

Ah. No thanks. New cars already bend us over a barrel for our data. I don't need you monitoring me 24/7 on my speed and location. I like the side guards on semis idea though. Run with that one, Wiener.

This tech should be developed and used to stop chase vehicles. Also if it is used to stop people from going 10 over then we shouldn't have cops checking people's speed anymore.

10mph over? Have they driven on CA freeways? The vast majority of traffic is moving at 15+ mph over.

This will cause traffic slow downs and more road rage.

[–] Landless2029@lemmy.world 29 points 9 months ago (1 children)

One interesting about speeding in traffic. Often you're rushing just to stop.

It's been proven that if you cap the max speed in heavy traffic everyone gets through it faster. Less stop and go with merges and guesses.

Think of all the times someone sped up to prevent you from changing lanes? Or someone blocks you during a zipper merge.

Traffic wouldn't suck as much if people didn't suck. I can't wait until a few decades from now we've got AI cars Managing it for us.

[–] rmuk@feddit.uk 9 points 9 months ago* (last edited 9 months ago) (2 children)

Variable speed limits just keep the road ticking over and they're great. In the UK there were a bunch of highway improvements being rolled out, like reversible lanes, traffic flow monitoring and, yes, full-time variable speed limits and they all worked really, really well. But they also got rid of the hard shoulder (refuge lane) and the whole thing was collectively referred to as "smart motorways". Needless to say that lots of people were injured or killed by the lack of hard shoulders, so now the government is poised to announce a rollback of all the smart motorway measures, including the absolutely superb variable speed limits.

Since a lot of discussion is happening around how they're going to implement this, and the article doesn't go into the details, here's more information: https://sd11.senate.ca.gov/news/20240124-senator-wiener-introduces-groundbreaking-bills-slash-california-road-deaths-epidemic

In line with NTSB recommendations, SB 961 requires every passenger vehicle, truck, and bus manufactured or sold in the state to be equipped with speed governors that limits the vehicle’s speed based on the speed limit for the roadway segment. The maximum speed threshold over the speed limit for that segment that the speed governor may permit the vehicle to travel at is 10 miles per hour over the speed limit. SB 961 also permits the vehicle operator to temporarily override the speed governor function. SB 961’s speed governor requirement does not apply to emergency vehicles.

And if anyone really wants to dive into it, the actual text for the bill is here: https://leginfo.legislature.ca.gov/faces/billTextClient.xhtml?bill_id=202320240SB961

[–] kibiz0r@midwest.social 16 points 9 months ago

Lots of people arguing about the practicality of this, or whether it can be done without invading privacy or slippery-sloping into mass surveillance.

The thing is: Even if it could be done perfectly — giving instant leeway when emergencies occur, being perfectly private forever, with perfectly accurate sensors — I still don’t think we’d want it.

That’s because laws are not just mechanical things. They are social things. When we put up a speed limit sign, it’s not just to configure a number in the driver’s mind. It’s to remind them to think about how they’re interacting with the community around them.

De-emphasizing that responsibility runs counter to this social purpose, which I think we intuitively understand at some level even if we reflexively bring out other claims in order to object to the policy.

Isn't that just going to cause accidents? For all the non regulated cars on the highway, what happens if you need to merge into a lane where the flow of traffic is faster than the speed limit? It doesn't even have to be a highway, but lane changes in any city can have that problem I imagine.

Has Scott Wiener ever driven on a freeway with clear traffic?

[–] dlpkl@lemmy.world 12 points 9 months ago (4 children)

What about if it was some type of close range radio signal or passive transmitter that communicates to your car when speed limits change?

Then again, when I was in Germany the car I rented had the posted speed limit displayed on the digital gauges. Maybe a GPS system that brings up the speed data for the road you're on.

OR, what about a visual camera system that limits the car to the posted signage?

[–] Waraugh@lemmy.dbzer0.com 11 points 9 months ago* (last edited 9 months ago)

The cameras on my Kia read limit signs and displays the sign on the dash. I can set my adaptive cruise to change speed based on the posted signs. I have to make a 8 hour drive six times a year and that adaptive speed changing is bliss. I can even set it to posted speed +5 mph. The display will even show a yellow school zone bar on the bottom of the speed limit sign on the dash. It’s surprisingly fancy. It even picks up charges based on construction so I know it’s using the cameras and not gps.

I'm currently in a rental that reads street signs and keeps the limit on the dash. Very handy for double-checking when you're suddenly not going the same speed as traffic. https://en.m.wikipedia.org/wiki/Traffic-sign_recognition

[–] Patches@sh.itjust.works 14 points 9 months ago* (last edited 9 months ago)

Had a Budget truck like this.

Going 70 down the Interstate when it saw a 15mph sign for a weigh station. Truck started slowing down real quick. It scared the piss out of me, and almost caused a huge pile up.

Fuck that shit.

[–] Death_Equity@lemmy.world 10 points 9 months ago (1 children)

In my experience with them by Dodge is the speed is wrong often enough where it can be a problem.

Saying 25mph when it is 45mph is one thing, but the 45mph when it is 25mph is another. There are a few rural roads where it said 30mph when it was 55mph. I would see the speed on the dash and think it was an odd speed for the road and Waze said something other than the car, so I would be in this total state of not knowing to trust the car, myself, or Waze. Eventually I just started to ignore the car and use my experience and observations weighted against Waze.

If it were a perfect system, that'd be cool.

I heard that some countries have zero leeway for speed limit trespassing, like if it says 100 and you go 101 that's a fine time. I don't understand why that's not the case in other places, why not increase the limit by that 10 mph/kmph you allow now and stop allowing speeding at all

[–] Crisps@lemmy.world 10 points 9 months ago (1 children)

Because car speedometers are not calibrated by law, and can be off a few percent. Changes in temperature can change tire radius as well.

After all that you then get into court proceeding of proving speed gun calibration has to be perfect.

So this reminds of this book I read called The Circle, in which everyone's fascination with technology and tracking and data collecting slippery-sloped at breakneck speed into 1984, except any stranger with an internet connection became your Big Brother.

We have many other environmental ways to encourage people to drive slower, like narrower lanes, or those long thin rumble-strip-style speed bumps, or landscaping with greenery.

BTW, why is it so hard to get information off google on traffic calming studies for freeways? Everything is about urban or suburban areas, smh. When I use "freeways" in quotes, suddenly I get a whole bunch of irrelevant results about people trying to get over their fear of driving on the freeway. Wtf google.
