Do you really need to overtake someone doing 130 km?



No, at least not for me: My plan is buying the Model 3 and then engaging the autopilot in such a case - and just travel behind whoever is driving with 130 km/h in front of me.

So for me - a reliable autopilot for the Autobahn is much more important than the top speed.


My reply has been downvoted to oblivion. Let me try again.

1. Tesla autopilot has a disengage rate of 182 in 550 miles. This cannot be safe in anyway for any kind of driving http://blog.caranddriver.com/in-the-self-driving-race-waymo-...

2. Apart from the fatalities there have been many other accidents with Tesla https://arstechnica.com/cars/2016/05/another-driver-says-tes...

4. Check YouTube for any number of autopilot crashes


Do you want to die?! Do not use the Tesla autopilot unless you are in a medical emergency and cant operate the vehicle.


On the Autobahn.. Yes.


Why?

Do you have a limited amount of time you can stay in the autobahn as opposed to a French or Spanish motorway, forcing you to speed up?

Or is it that you just want to go 200Km/h and it's not about overtaking safely?


No its about following the rest of the traffic. In the unlimited sections, traffic is 130++ km/h (up to 200-250 in overtaking lane), So if you are slower, changing lanes, overtaking etc. becomes less safe.


One thing I noticed last year when driving in France for the first time, compared to the UK was that there was a much greater difference in speed between the lanes. I imagine the difference would be even greater on the Autobahn. In the UK, the motorways have a speed limit of 70mph, and most people actually do it - very large vehicles are limited to 60mph. So emerging from the left lane to go around something slow only involves adding 10mph or so. In France, the right lane is often limited by a lorry going at 90km/h, while the left lane is at 130km/h. Emerging to go around something (if you have the misfortune of having to slow down behind the lorry because the left lane is busy) involves adding 40km/h to your speed before the next car in the left lane catches up, which involves a lot more power to do safely.


> In the UK, the motorways have a speed limit of 70mph, and most people actually do it

Are you kidding? Try doing 70mph in the third lane of a non-busy motorway and see how long it takes someone too be dangerously close behind you.


That's something different. Of course there are loads of people speeding too.

One other thing I notice is that different motorways in the UK have different characters. On some, yes people do tend to stick to the limit, and on others not so much. I haven't spotted a correlation yet with the locations of speed cameras.


You can just stay in the slow lane if that's a problem. And doing 130 km/h in the middle lane is perfectly acceptable, people can just overtake you by using the fast lane.

I've never had the problem OP mentions, on the Autobahn...


But you were talking about overtaking, that's a completely different scenario (keeping up with traffic on the slow lane).

You're saying that any combination of car and driver than can't sustain cruise speeds over 130Km/h is a danger.


Wait, I'm not with the GP and don't think you NEED to overtake people at 130.. Why would you?

But I don't think you can't overtake safely and be fast. It depends on the situation and is, in my opinion, quite common. Most people drive sane, 130 or 200.


You don't have to but some people like to arrive earlier and drive faster. And many people I know don't like following other cars, so they'd rather overtake and drive 130 km/h in front of the other car than behind. This, however, changes with autopilot.


Driving faster on the autobahn (or any freeway/highway) will not get you to your destination much faster. The total transit time is impacted the most by city/local traffic and such. Unless you are on a 500km journey you are not saving much time going 180 (rather than 140) on the autobahn.


This is actually incorrect. When you ask a German how far away another city is, their first question will be: "What kind of car do you drive?"

The biggest difference is that in Germany, the speeds are more sustained. In the US, cars generally drive in whatever lane they feel like, so your speed is constantly changing. So even a difference of 180 vs 140 will be significant. (and it could easily be 200 instead of 120).


This is untrue. Are you seriously attempting to use a colloquial joke as some sort of evidence?

While Germans are a bit more conscious of driving in the left lane when not passing, what you are saying neither makes sense, nor is it applicable, especially in any amount of traffic.

It also totally discounts the vast amount of road construction and maintenance that Germans continually do on their roadways (infrastructure maintenance is a big deal). The construction alone, especially in Hessen/Rhineland Pfalz vastly impacts travel times in ways going 40kmph faster could never attempt to approach.


I've driven plenty in both the US and Germany and the road etiquette in Germany is light years ahead of the US.

If I choose to drive 120/130 on the autobahn I have a much higher chance of doing so continually than if I choose to drive 75 Mph on an Interstate highway in the US.

I'll give you my anecdotal evidence from last year's trip to Germany. I took a ~550 km trip, and while I don't have actual GPS data from my trip on hand, I do remember that I was able to drive roughly one third of the way in sections with no speed limit and no traffic/construction.

For 2/3 of the way my average speed (including traffic and construction) was 122, so that took 3 hours. For the rest (1/3) of the way I was able to travel with unlimited speed. Traveling 183 km at 183 km/h (average) vs. 122 km/h saved 30 minutes of my trip.


I'm absolutely relying on anecdotal evidence. But I spent more than a decade on tour with a band driving vans all over the US and Europe. I've been on almost every stretch of highway in Germany and America many, many times, and I was extremely familiar with travel times between cities in all seasons and conditions. So yes, still anecdotal evidence, but a whole lot of experience behind it.

Obviously construction (anywhere) affects travel time. But in the US the highways have more exits, cops running radar, and there's ALWAYS someone going slowly in the left lane. Unless you're in the western desert states, it's pretty hard to maintain a steady speed. By contrast, everyone in Germany knows how to drive, and everyone follows the rules about keeping right and passing left.


On the Trans-Canada - yes, absolutely. The limit on large stretches of it is 120, and in good conditions, traffic moves at 135-140.
