Gday
I am unsure what countries still use miles instead of KM
but I cant see most people needing over 125 Km/per hour
------------------
* 80 mph is 128.74 km/per hour
* 85 mph is 136.79 km/per hour
* 112mph is 180 km/per hour

I'm not pulling it from my ass. There are a lot of people who take their cars out on the track, I know quite a few that have. Just because it happens outside your bubble doesn't mean it doesn't happen. You're being unnecessarily rude and confrontational, which isn't justified despite you thinking you have the moral high ground.
>a lot of people Yes, maybe 0.01% of all people. I also used to do autocross, so I know people enjoy track racing, I just don't care because it's a waste of resources, bad for the environment, and not a good reason to get rid of speed limiters that would save lives. >You're being unnecessarily rude and confrontational I don't have to be polite to people who risk lives unnecessarily. You think you have the moral high…
I never said I oppose limiters in cars. I have one in my vehicle I have not removed.
> I'm trying to protect lives with very little impact to things that matter
I don't see what you're doing to protect lives by commenting on HN.
Stop throwing around that 0.01% stat you made up. More than 1 in every 10,000 people take their car to a track day at least once in their lifetime.
Re: Volvo is introducing a 112mph speed limiter to all its new cars
#203There is no circumstances under which a maximum speed of 112 would bother me. I drive a Honda Fit. I don't think I have ever driven it over 85 miles per hour (137km/hr). I'm not comfortable driving faster than that. What makes me mad is that my speedometer goes up to 140mph! Why?! The only answer I've ever seen that makes sense is that it's a marketing tool, but who honestly buys a Honda Fit and thinks to themselves…
I've always wondered the same thing - My theory is that at normal freeway speeds, the indicator points more or less at 12 o'clock, which is easier to see for a driver.
I think it's related to gear ratio and redline. My 89 Honda Accord LX-i needed around 3250 RPM to hit 70. The speedometer maxed at 130. If you extrapolate that's about right. I found out it was drag /horsepower limited to just over 100 but if it had the power the actual max before possible engine damage would be 130.
Of course this is based off one car so I could be totally wrong.

I drive a 392 challenger scat pack shaker... I don't think I've ever had it over 100, though the max is 201. I'm not sure I'd be bothered by a regulator for the top speed. That said, I don't think speeding is even close to the number 1 killer these days... Cell phones seem to be the leading cause of accidents these days. Maybe they should detect motion over 5mph and turn off display of messaging apps, only bluetooth…
> I drive a 392 challenger scat pack shaker... I don't think I've ever had it over 100 I don't see the point of a vehicle like this unless you drag race it on a regular basis. It has limited utility, is larger than an Abrams tank, guzzles fuel like it's 1998 and couldn't make it around a slalom cone course even with a skilled driver. It's a make a lot of noise and go really fast in a straight line car. That's what it…
It’s a five seater that is comfortable for a tall person, with classic muscle car looks, cruises nicely, can accelerate half-decently and has a throaty sound.
I don’t have the 392, but a 345, and no other car hits those same bullet points.

I mean, I get by with an EV limited to 88mph (not sure if that's a in-joke or what). It gets to 88 really fast, but can't go faster. Probably saves me a ton of battery and I still cruise or lead on the left lane. 112 is 25% faster, way more lethal. I'm guessing it's 112mi*1.6km/mi = 180kph.
> an EV limited to 88mph Which one?
Ford Focus EV. Got a massive deal on it back in 2017. Pretty happy with it.

it's fun to drive entertainment has value to some people
I get it (I'm an amateur race car driver). What I'm saying is, OP is not using the car to it's full potential.
Most people don't use things to their full potential. We have cars with larger engines than needed, CPUs and memory banks that rarely stay above 90%, food that gets tossed out daily, laundry washed and dried at half capacity and below, and so on. Many developed nations would look differently if we used everything to their full potential potential.
Re: Volvo is introducing a 112mph speed limiter to all its new cars
#207Although 180 km/h looks reasonable, I'm not convinced this kind of solutions is the way to go. Speed limiters are not new and were sold on the idea that are improving the efficiency of the engine, burning the fuel better. To do the same thing in regard to safety however, is a bit humiliating or at least patronizing. People already are required to jump through non-trivial hoops in order to legally get behind the drivi…
I don't think it's fearmongering, especially when you consider that children are allowed to drive (at least here in the US, and with minimal training). This isn't about being a nanny state or keeping folks from driving fast cars (I imagine there will always be cars you can take on the track), it's about keeping everyone on the roads safer. Not one single time in my highway driving life have I encountered a NEED to dr…
This is exactly the kind of argument I tried my best to prevent when I said that we already have speed limitation both on the society level and on individual one. You may rise the bar for the amount of training required for children in the US, you may restrict the speed capacity of the vehicles they'd be allowed to drive, you may disallow them to enter the kitchen for the fear of knives that they might find in there, you may even keep them in the leash until you'll deem them ready for the world out there (if ever), there are a lot of options that would address the problem a more localized manner instead of some global restriction "just in case". I'm not talking about the specific limit Volvo has chosen for their cars, because for the most part, the specs of the cars they make are theirs to decide, after all. What I'm talking about is an automaker promoting speed limiting as necessary for safety and about the voices that endorse that as reasonable. If the safety indeed requires an improvement through additional speed limitation, that would have been addressed by the bodies of society whose job is exactly that public safety, and by further adjustment of our driving speed on the individual level, considering the self-preservation instincts (which are supposed to checked along with the rest of one's mental condition prior granting the driving license).
Re: Volvo is introducing a 112mph speed limiter to all its new cars
#208If I were automaker I'd consider allowing bursts above the maximum speed limit for a few seconds. I'm not a fan of limiting (besides for warranty, electronics reasons) and prefer to educate rather than restrict. However, if taking this approach I believe you should consider that some people might drive in the limit and they deserve to be in power of their vehicles regardless. Imagine if you drive near this software-l…
At 112mph you’re traveling 54 yards (50 meters) per second . There’s no situation that can be solved by increasing speed at this velocity. You simply won’t have the time to react. Unless, of course, you’re trying to outrun a train in a car chase in a movie.
You might need to escape a tsunami, pyroclastic flow, forest fire, or hurricane. The road might not go in the ideal direction, so being just a bit faster might not be enough.

Doesn't this stopping distance depend on the car? Said German cars have bigger breaks and bigger tyre surface and have been proven to stop quicker. Top Gear showed this often (Australian trip with the m6, Bentley and gtr) all stopping in less than half the Highway Code distance...)
Stopping distance does depend on the car, but physics has a bigger influence. The kinetic energy in a car is 1/2mv^2. No matter what car you're in, going twice as fast requires dissipating four times the energy in order to stop. So, take a sporty car with twice the braking performance of a basic car, and you can go 1.44x as fast as the basic car while still having the same stopping distance. I have a very light car t…
Might not be pleasant but guessing hitting something would be less pleasant...

> But the big problem is the roads and the culture around speed. America doesn't have either of those things, and probably never will. A culture of safety is not a "big problem" IMO. The "big problem" is that a vehicle at 120mph requires an insane stopping distance. On dry asphalt: * 60mph: 172 ft * 120mph: 688 ft [1] http://forensicdynamics.com/stopping-braking-distance-calcul...

The 100 km/h stopping distance of a BMW M5 is ~30m, compared to 41m for a Honda Fit.
https://fastestlaps.com/lists/top-quickest-stoppers-60mph
That's a pretty good performance (but it's a $100K car), but at 200 km/hr, the stopping distance of the M5 increase to 124m (which makes sense since a 200 km/h car has 4X the kinetic energy of a 100 km/h car)
Once out of the specialty racing cars, all of the cars "faster stoppers" list took about 27m-30m to stop from 100 km/h so that seems about the best that can be achieved today.
