Interesting report from the Insurance Institute for Highway Safety. Says that they are helpful but not perfect and often fail. BMW 5 series seemed to stop operating and cross the line the most. Mercedes seemed to do better than Tesla, BMW and Volvo. Here is a link to the report:

http://www.iihs.org/iihs/news/deskto...ad-track-tests

This echoes my experience. In testing the lane centering systems, the report found that the BMW often lost the guidelines (my experience as well) and crossed the line most frequently (again, my experience).

None of the tested vehicles did great but in my read, the BMW system did not do well (the safety feature did somewhat better).

Assume they tested with hands off to see what they were capable of. As intended with hands on its ok but not perfect.
Glad the safetyfeatures are good though.

I ask the bmw geniuses if there were any updates for lane assist but they said not.

This is only the beginning of "real world" evaluation of such systems. The state of our roads, including how they are marked and how much gets rubbed off over time, will weigh heavily on the autonomous hype.

It works well here in Denmark - but again mostly on freeways is where I find it useful.

Now one thing I don’t understand is - why is there no audible tone or something to alert you when it looses the ability to follow the road? In the HUD you only see it turn grey, and you really have to watch carefully.

I understand it’s only meant as an assistance tool, and that hands on the wheel is required. I still think some sort of ‘beep’ would be useful though, making you aware.

YEP I love driving Cars, not being driven, so these systems are not for me.
I will maybe when i'm 90+

Surprised to see that they omitted Audi, the only company with a L3 semi-autonomous car.

Too new.

After buying a 5 series, E-Class, Tesla 3, Tesla S and Volvo S90 they ran out of money and couldn't afford the Audi to include in the tests.

Glad my car doesn't have any of these nannies. I believe they are not fully baked yet and still a ways off from prime time. I am sure the next one will have far more improved and less error prone driver assistance systems. For the time being, nothing replaces full attentiveness and awareness in part of the driver at all times.

Well said.

Our crumbling road infrastructure will not enable these systems to work any better or as intended.

Just came back from Europe and their road infrastructure is generally much better and well maintained than US highways. It's embarrassing.

I was in Copenhagen last week and the motorways are excellent and people generally, like in most of Western Europe, know how to actually drive. Now driving around the center of the city is a different story. Lots of traffic and many bicycles but they seem to co-exist happily with each other. Here in the US we are so behind the times in comparison to Scandinavia, is not even funny.

[AP]

Yes standards good but certainly not perfect, in the U.K. more than enough bad drivers out there. Falls into 2 categories of dangerous and inconsiderate( ie hogging middle lane on motorway when lane 1 is empty)
Road conditions in the U.K. are getting worse down to not spending money on them.
Road markings suffer which gets us back to lane assist where it can struggle.

Yes, no doubt city driving can be chaotic. While cars and bicycles generally co-exist well - in large due to focus on creating bicycle infrastructure and prioritizing bicycling in the city - you often find bicycle riders who drive like crazy, so you really have to watch out. I guess the same can happen with vehicle drivers though .

I spent 10 years in the states and I miss cheap cars, big engines and motorcycles - less so the drivers or roads. We’re not dependent on cars the same way either, so it really will be interesting to see where automated vehicles takes us. I think our public transportation service will be some of the first to adapting it.

A study in the 1970's compared different modes of transportation in the US and rail was found to be at least 10 times more expensive per rider-mile than small econobox cars and infrastructure. This makes sense since there is no system in the US to my knowledge that is not at least 50% publicly subsidized due to the universal shortfalls from ticket sales.

As for autonomous driving and public transportation, it will be interesting to see if public transportation doesn't take a huge hit from loss of ridership. We'll see.

And I am sure that the cost of roads and road maintenance was not factored into that calculation. GIGO.

Roads in the UK are going down hill fast, many are a disgrace and an embarrassment TBH.

It'll improve with the blue passports

No, actually, I believe it was. But be careful: we can't go without roads so they are a constant. The cost of train land, mechanical, and energy is quite high especially when ridership is not maximized.

Here is a more modern look at costs per passenger mile for comparable modes of transportation.
