And another nail in the coffin of the EU. Annoying your voters, great way to salvage your sinking popularity.

I don't understand the downvotes. The surveillance potential of this is _massive_ and dystopian.

People life authoritarianism when it’s “their side” doing it.

Is the category of "deaths from speeding" large enough to justify any action whatsoever? Are "deaths from speeding" typically single vehicle or multiple vehicle accidents? Why does the Autobahn still not have speed limits on large parts of the road and why does this not cause massive problems?

But what actually causes crashes?

Speed alone does not cause crashes It's reckless driving, distracted driving, poor driver training, drunk or otherwise inebriated driving, poor road design, drivers suffering medical emergencies behind the wheel, etc

Why so much focus on fixing speeding and so little on training people to be better and more responsible drivers? Or removing terrible drivers from the road?

Yes, I stay to the right too unless passing or exiting to the left, etc, for the reasons you said and others too (the right lane has a shoulder next to it, increasing options in an emergency) Still gets you passed a lot if you're unnecessarily slow though. If the prevailing speed is a speed I feel unsafe going, then sure, I'll accept the passing. But if the prevailing speed feels safe -- it might just be 5 MPH over t…

Well 5mph isn't really speeding; as far I know they set the speed limits 5mph lower than they really are (e.g: 55mph means 60mph). But trust me, the imaginary police are very much not imaginary. I got a couple speeding tickets before I decided I wasn't going to deal with the courts ever again. Now, I do the speed limit. I see cops everywhere on the highways in my state and they definitely will pull you over going 10-…

> Well 5mph isn't really speeding

Hold on now, that's just an opinion. And while it happens to kind of match mine, everyone's opinion on how much speeding is "really speeding" is kind of different, up to a point. Kind of proves my point-- I don't want something stopping me from doing 5MPH or 10MPH or even 15MPH over the limit if circumstances outside of my control indicate I should (NYC is a good example of an area where EVERYONE going 15mph over the limit is not unusual)

My personal rule of thumb is to make sure at any given time, considering yourself and the drivers near you in view on the highway, that you are either under the speed limit or at or below the average speed everyone else is going.

If everyone else is going 10 MPH above, go 8 MPH above. As long as most drivers near you are faster, a cop will pull one of them over first. Never go above the speed limit without a "Speeding Buddy" (a driver who is going even faster who is a few car lengths in front of you). If you have no Speeding Buddy, you don't need to speed, you can just go the speed limit.

So if every car is following the speed limit, that is going as fast as they are allowed, why would any one person be passing someone else?

Perhaps parent isn’t talking about that scenario. But surely you can imagine a different scenario where this applies, right? Maybe Grandma Jones doing 10 under the limit on a two-lane road?

They're either so slow that they're easy to overtake, or they're so fast that it doesn't matter to stay behind for a while.

So just relax, the time lost is minuscule.

Not quite. 8k of those are motorcycles. 8k are pedestrians. Half of those are drivers who had drugs or alcohol in their system. One quarter are male drivers under 25. Most fatalities happen at night.

> and speed (really momentum) is a large factor in the lethality of crashes.

Not quite. It's mostly lack of seatbelt usage.

> Most speeding issues do not occur on highways, but on local roads.

Not quite. It's about 50/50.

To add to all of this, more people die on Texas roads than California roads. Not per capita, but TOTAL. California has 10m more people in it than Texas. This alone should give pause.

> You have no sympathy for me when i find myself driving amongst others who drive above the limit? I also often find myself driving among other people who speed. I stay to the right with the OTHER drivers who are following the law. I always drive the speed limit and it's never a problem for me. Many states' laws require this, anyway (faster traffic to the left, slower traffic to the right).

Yes, I stay to the right too unless passing or exiting to the left, etc, for the reasons you said and others too (the right lane has a shoulder next to it, increasing options in an emergency) Still gets you passed a lot if you're unnecessarily slow though.

Because k = .5mv^2. Even 5mph makes a big difference. Most people don’t have a good intuition for this, but it’s especially relevant when on streets with pedestrians.

This might be effective if all existing cars on the road were somehow retrofitted with speed limiters. But what we'll see instead is an even more dangerous combination of people in older cars (the majority of cars) speeding while people in newer cars are causing a dangerous speed differential in the flow of traffic. Not to mention the economic impact this could have on on new car sales when people decide en masse that they'll just hold onto their old cars without limits for longer.

Hardly because they didn't exist widespread before. Speed limits on the other hand are proven to reduce accidents.

> Speed limits on the other hand are proven to reduce accidents. There have been speed limits on every road in the US for over half a century; how did they conduct a controlled study?

Because speed limits change and it's easy to measure the before/after impact in terms of the number and the severity of accidents as the average speed in an area changes.

Leaving aside the concerns about the tech not working well, I'm really not a fan of this pre-crime stuff. This feels very Big Brother, where someone (or some system) is watching over you so you don't break any laws. Things like this lead to cultural ossification and are a nightmare scenario for me.

Is it "pre-crime" if it activates once you are speeding? Surely we can agree that is a crime

Is it a crime where "100% enforcement" is worth surrendering (even more) individual privacy?

In most EU countries(and UK) you have different speed limits based on the class of the vehicle. So for example in the UK on a single lane road a regular car can go 60mph, a car towing a trailer can only go 50mph, but a heavy goods vehicle(over 7.5 tonnes) can only go 40mph. So on most roads that aren't dual carriageways you constantly encounter a situation where everyone is driving at their top legal speed limit but…

Under that scenario, assuming 10-20mph differential is sufficient, overtaking by faster-class vehicles hasn’t been affected. Slower vehicles presumably shouldn’t be overtaking anyways, except when dealing with… even slower vehicles (but the joys of trucks overtaking each other by like 2mph difference and blocking the whole road for 10 minutes)
