> The german Autobahn is famous for having no upper speed limit

30% of the Autobahn have a mandatory speed limit for varying reasons, mostly safety (high incidence of accidents for example). On 70% there is an advisory speed limit of 130kph.

This means, it is inadvisable to exceed this speed even under the best of circumstances. Now in practice this has very little meaning. You may speed with impunity.

Until there is an accident. Then if a driver has exceeded the 130kph he will invariably be assigned a higher liability for consequences of the accident since the driver accepted the increased risk for accidents by operating the vehicle at a speed above the advisory speed limit. This is even true, if the other party to the accident is completely at fault. The only exception would be, if it can be shown beyond a doubt that the accident would have happened at the recommended speed of 130kph as well. In practice this is next to impossible.

There have been several attempts to change the advisory speed limit to a mandatory speed limit. Albeit the arguments aren't clearly on the side of the proponents. Regarding accidents, a statistic from the German autobahn ministry in 2018 stated that 71% of all deaths on the autobahn occur in places with no mandatory speed limit. Since 70% of the autobahn have no speed limit, one might wonder, what the expected result of a mandatory speed limit is expected to be.

In addition 33.6% of all kilometers are driven on the autobahn while only 12% of all deaths occur on the autobahn. 60% of all traffic deaths do occur on rural roads which have speed limits throughout.

Regarding climate change argument, the estimated reduction of total CO2 with a mandatory speed limit of 120kph would be 0.2% or even less if the mandatory speed limit were 130kph.

A visit to the neighbors Austria and Switzerland (both have speed limits on the autobahn) would also destroy the expectation, that smaller cars would be bought, if there were a mandatory speed limit on the autobahn.

I don't really have a stake in the matter, but as your response clearly shows even just mentioning the topic triggers vehement defenses. You clearly have done your research though, so I respect your argument.

What I will say however, whenever I drive on the german Autobahn at some point it happens to me that I'm in the left lane to take someone over and another car comes speeding towards me from seemingly kilometers away at the speed of a damn rocketship. Whatever the hard numbers may be, this causes high amounts of stress and makes me feel very uncomfortable on the road every time. Not a good state to be in while operating high-velocity death machines!

[Joe-Z]

@FDSGSG: That's why I said "from seemingly kilometers away". Like, I base my decision on if I have enough space to take over by assuming reasonable[0] speed levels and suddenly someone comes along going 250 km/h

[0] I guess reasonable in this case means what I'm used to from driving on other countries' highways

EDIT: Sorry, I changed my response while you were actively responding it seems! You can call me a bad driver all you want. The fact is that the rules should be made to accommodate bad drivers also. Survival of the fittest is not a good rule when it comes to traffic law!

[FDSGSG]

Yeah, but you know very well that many people drive 250km/h on the autobahn. If you decide to assume "reasonable speed levels" and try to overtake someone in a corner that's just you being a bad driver.

But sure, maybe the rules should better account for bad drivers.

E: > The fact is that the rules should be made to accommodate bad drivers also. Survival of the fittest is not a good rule when it comes to traffic law!

Of course, but people also need to take personal responsibility for their actions. Statistically the autobahn is quite safe, it's not clear that adding global speed limits would make it much better. It's very difficult to balance this possible minor safety increase with the fact that many (perhaps even most?) people find it vastly more comfortable to drive on the autobahn as is.

There are places where I refuse to drive because I'm not comfortable with the environment, there's no way you'll find me driving in a city like Barcelona or London. Perhaps you should do everyone (especially yourself!) a favour and consider the same in regards to the Autobahn?

[Joe-Z]

For some reason now I have a reply button again. I want to use it to tell you that I find your suggestion based on the remarks I made here very rude. The driving skill you infer on my part probably says more about your interpretation of my comment than on my actual ability to navigate a vehicle safely. That said, I detest cars and wish cities were free of them. THAT said, I never posted this to take any stance on the "global speed limit on the Autobahn"-topic, so this will be it for me.

Thank you for the discussion!

[FDSGSG]

Rude? I think you’re just being thin-skinned.

You yourself admitted to driving dangerously by overtaking in corners while ignoring the prevailing traffic conditions, for some reason you’ve now edited that part out.

Pointing this out isn’t an attack on your character. I’m a bad driver too, I get far too stressed out while driving in busy cities so I just don’t do that.

[lobotryas]

If you as a driver or your vehicle cannot move quickly enough to overtake another car on the autobanh then the fault is with you. That “rocketship” behind you should not have to decelerate because of this. The other poster is right: you are at fault here.

[wink]

No, you are wrong here. §5.2 StVo[0] says (my bad translation) "You may only overtake if your speed is significantly higher than the one being overtaken."

So let's assume the one you're overtaking is going with a solid 100. What's significant? Let's say 150? +50%. The one approaching with 240 is still the perceived rocket ship.

Also, just for completeness, here's a blog post about some case[1] where the speed was being judged, 10km/h is barely enough. So let's be generous and change my example to 100+120.

It sounds like you're doing something wrong if this happens regularly. Either you're overtaking without paying attention to your surroundings or you're overtaking cars your vehicle isn't reasonably capable of overtaking.

Going slow on the fast lane is supposed to be uncomfortable.

Does that make any difference if you’ve got reasonably good insurance?
