> I'm not comfortable driving faster than that. Of course you're not comfortable driving faster than that in a Honda Fit. That's like saying you're not comfortable going faster than 30 in a golf cart. In the right car and on the right roads, hitting 120 is as simple and easy as hitting 70 in typical econoboxes. And actually, I'm not even talking about a Porsche 911; more like, every German car, especially Audi/BMW/Me…

> 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.

I think my broader point is really that, as assistive tech continues to increase in reliability and deployment breadth, Speed is something we as a society should consider raising.

German cars are feel AMAZING at high speeds. They're not the only ones, but dollar for dollar its easier to take a German car to 120 than any other nationality. Why? Because they're made to be driven on the Autobahn. They are, all else equal, safer to drive at high speed than American or Japanese cars because Germany has a stronger culture and laws around allowing cars to drive fast.

As we add assistive tech, it becomes safer to take cars this fast. Of course, there's a lot of other things to solve; roads, adoption, etc. And we can't solve the physics of stopping and impact force. But the benefits might outweigh the costs.

But Volvo, if we take them at their word, is saying "we don't care. This is as fast as you can go. Enjoy."

And sure, maybe their speed limit is fast enough. But, really, this move is just posturing. The tangible effect that it will have on vehicle safety likely won't be large; at best, it might stop some dumb kids from taking their dad's car out for a joyride and driving it off a bridge at 130, but its not going to stop them from doing the exact same thing at 100, or even 60 (on some backroads that speed is just as deadly).

When they limit their top speed, what they're also quietly saying "these cars are only engineered to go this fast". That engineering is why German cars are so great to drive in the triple digits. Its not just the platform; Volvo has computerized assistive tech. Is it tested to actually work at triple digits? Probably. Now that they have a corporate-wide mandated speed limit, will they continue to develop and test it at triple digits? I don't know.

And that's the real disappointment. We're now just "alright" with the speed we've always been driving. Cars could become "personal bullet trains". With enough assistive tech, give certified models their own barriered lane and, if the weather conditions permit, let them go 140. But Volvo isn't interested in that future, and that's very sad indeed.

German here. I once drove an Audi A8 from Hanover to Berlin (while working for a car rental company). It was pretty much 250kph (155 mph) all the way (except where there was a speed limit of course). Definitely an insane experience. My hands were extremely sweaty. Yet I couldn't stop driving that fast. In that type of car, you don't really notice it anyway. But you DO notice it when suddenly another car is getting in…

You driven like that once, some people drive like that daily. Usually it’s not them causing accidents. Whatever, anyone can be fast in a straight line.

> Usually it’s not them causing accidents.

I hear that all the time, do you have a source?

Meanwhile, I find that acceleration has helped me to avoid accidents numerous times in my ~17 years driving. Everybody has different experiences.

Then you're probably a much worse driver than you think you are. Sorry.

I struggle with people that think driving fast makes them safer drivers. And I've never seen any data supporting that claim.

In the current climate regarding the speed limit in Germany? Good luck. It’s from experience, you know, seeing it from the perspective of the fast driver. I know it’s another slogan but driving slower makes one more suspectible to distraction.

I don't want Volvo, or a computer, or a mechanical system to kill my family because it didn't account for an edge case. Everyone here is talking about normal highway use, but, as everyone knows, not all situations are normal. Bad things happen. My imagination is limited, but for example: Fires can spread quickly and surround you (e.g. a valley with one road out), a tsunami can happen with only a couple of minutes war…

I find this argument rediculous. We should not allow a huge negative behaviour every single day, just on the off chance that there’s a possibility it would restrict us in a very unusual event. Hundreds of people should die because maybe we can save a few? Makes no sense.

How many auto fatalities are a result of people driving 150? Almost none, I'd wager. So then is my argument still ridiculous?

Freedom has value. Just because we can force some people to do some things more safely in some cases doesn't mean we should always do it. Otherwise, we can just outlaw cars entirely and force everyone to only go places where rails take them at government-approved speeds.

Geography and equipment do not change your ability to react to events. I've driven 180-200 km/h on the German autobahns (in a car that could handle it) and I could tell I was driving at the edge or slightly beyond my vision and reaction time. It was freaking scary. I don't know if every driver out there could tell when they were hitting that limit. The golf cart analogy doesn't apply here IMO.

Are you talking about curving roads? 220 km/h is no problem on straight flat stretches.

There are accidents, but fatality on autobahn about 40% lower than U.S highway.

With that said, I wouldn't really want to do sustained high speed driving anyway due to fuel economy. Going from 100kmh to 180kmh, fuel economy drops by half.

I think your whole premise here is, North American speed limits would go up if only we had enough cars that felt good at higher speeds?

If so, I don't think automotive performance and lack of "smooth feel" at high speed are the things governing our speed limits.

My Ag Science teacher used to say that. (not so much about collisions, but other incidents)

Definitely. Like, there's no such thing as a gun accident. If someone ever accidentally gets shot, it means someone wasn't following one of the prime rules of gun safety.

There have definitely been recalls/warnings for firearms which have misfired without anyone's finger on the trigger.

A fine example of segmentation. Most Volvo customers don't buy Volvos because they're fast cars. They buy them because they are safe cars.

Well, there is their Polestar [0] performance division, which suggests there is such a market...?
