It depends on the system. First, Google maps is very good at estimating journey time on roads like that, and gets the actual practical speed right, so it is possible. But second, the Tesla autonomous driving system doesn't depend on the road being mapped in detail. There's no geofence keeping Teslas in a specific mapped area as there is with the other system.
 
I live in an area that will be very tricky for self-drive cars unless many, many roads and lanes are removed from their navigation systems. Currently lots of people even those more familiar with the area won’t use satnav if going somewhere new as the satnavs treat many of the one lane roads as “fast” roads as the nominal speed limit is the national speed limit I.e. 60mph, whereas you’d be pushing your luck to even go to 30mph and probably at some point have to reverse back to a “passing place” which is usually a small section of the road where it has been made wider by cars constantly brushing against a hedge. There is zero probability these roads are going to be converted for self-driving cars.
Same here. Full self drive would be a pipe dream. Single track roads and/or no road markings. It's largely impossible to determine where the edge of the road is. There are often floods across the roads and in the summer bracken can make the lanes appear impassible.

Add in dopey pedestrian tourists and their hounds, escaped sheep, cyclists and equestrians and any respectable self drive vehicle would throw up its virtual hands.

There's a stretch of relatively wide straightish road up the hill from here, no exaggeration but every year you will see at least a couple of cars in the ditch, not usually from excessive speeding* but from being a polite driver pulling over to let other vehicles pass and not knowing about the concealed ditch on one side on the road.

*You can spot the excessive speeding ones, they are the ones on their roof in the ditch!
 
wonder when spoofing self-driving navigation will become a sport. Making navigation software like Google Maps think that there's a traffic jam when there isn't is rather trivial. I'm sure it's not much harder for a Tesla.

Why would you spend time and effort deliberately ◊◊◊◊◊◊◊ things up for other people like that?
 
I think it would be helpful if people in this discussion watched some of the videos of Teslas being driven with supervised autopilot. They don't need lane markings and I've seen them handle dirt tracks. I've seen one leave the road and go up on a grass verge to avoid an accident. Navigation software is just navigation software. The car doesn't drive at the speed Google tells it to drive at, it follows the instructions or the car in front (like a sophisticated ACC).

There's not a lot of point in speculating when people have misconceived ideas about how this works.
 
Why do people write computer viruses?
Various reasons.

I was the proud recipient of what I believe to be the first reported MS Word macro virus, "Concept", in Australia. I was working for the Department of Defence at the time. One of its components was called "Payload" which contained one commented phrase: "I think this proves my point".
 
There are people walking along roads all the time. I'd have thought there was some way to distinguish between phones in cars, phones on bikes and phones in pedestrians' pockets.

But none of that is particularly relevant to self driving cars.
 
Oh, if you meant more dangeorus than public transport, then I agree with you of course.


Not sure what your point even is here. My point is that no matter how much new urbanism catches on and we manage to make cities for people, not cars... We still need cars, and self-driving cars are going to be safer than regular cars. And even if you were to somehow make the point we don't need private cars... Deliveries? Emergency vehicles? Mail? People living way farther than 20 minutes from the nearest bus stop or train station? The list goes on.
My point is that able bodied people don't need cars for the last mile.

The rest of your argument is a straw man. Nobody is suggesting we do away with cars completely and certainly not delivery vans. There will always be cases where these forms of transport is needed but we definitely need far fewer cars in our urban centres.

I'd have to disagree with that bit. Often it has sent me down country lanes that are marginally shorter routes but take a damn sight longer. Google maps seems to have no clue about the quality of the road. just its theoretical speed limit.

It will use the official classification - "a" or "b" and the speed limits.

Yup, and if a single-track lane and a decent road are both classed as 'B' then it will send you down the lane if it happens to be shorter.
WIll robocars do better?

No because they use the same routing info as any of the satnav systems do.

Are we seriously talking about the same product, used over the past year? I have been gobsmacked by how good it is. Barring rapidly-developing traffic issues its ETA is almost spookily accurate. It knows damn well what the practical driving speed of a road is. I used it in the north-west Highlands in September on single-track roads and it always got the ETA right. I got the feeling it even knew the times of the Corran ferry. It's amazingly good at finding detours round hold-ups. It once took me off a jammed-up M8, steered me through the spaghetti hoops of the Livingston roundabouts then back on to the motorway, but six minutes further forward in the queue than I had been.

I know it wasn't so good years ago, but now I wouldn't be without it. I just plug my phone into the car (Android Auto) and I know when I'll arrive. On a long trip I set the next charger as my destination and titrate the miles remaining against the car's remaining range to arrive in good order on about 4% battery. I think it's bloody brilliant.

But actually, I don't know what this has to do with self-driving cars.

Yes, to the first point. In country areas it's prone to sending me down narrow lanes when it spots a 'short cut'

To the second point - I've learned to ignore certain 'short cuts' as I know they're trouble. Will a robocar be able to learn? Also, if I end up on such a lane I can keep my eyes peeled for places to pull in, such as field entrances, in case I meet an oncoming vehicle. WIll self-driving cars be able to do that? Maybe even reverse a good distance to avoid a standoff?
 
I live in a country area and mostly drive in country areas and it's never done that to me. It only scopes out these lanes when there's a road closure on the main road.

A 5-minute traffic delay on the main road ahead so it reckons the lane is quicker, when in fact it's slower and a minor nightmare to negotiate? Dunno, I can only describe what has fairly recently happened to me a number of times.

Around here we are crisscrossed by so many little lanes its quite unbelievable and my satnav seems to be trying to make sure I've gone up and down all of them! One of the worse ones locally is the very, very steep lane directly off the main road, it is a single lane with a couple of passing places, at this time of year it is particularly lethal as it gets full of wet, slimy leaves that are worse than ice for slipping and losing traction. Seen people in tears trying to get up or down, and like most locals over the decades I've had to get into someone else's car to help them out. It's not as bad as it used to because a lot of cars now have these "hill start" features but the satnavs still love it - in terms of distance saves about a mile and half compared to a "detour" using more normal roads. Oh and it is a 40mph lane. Really would like to see 2 self-driving going opposite directions negotiate it.
 
My problem is that I just get all contrarian when a voice tells me what’s the best route.
I automatically get the “I know where I’m going” attitude and stop listening to the voice.
It’s a me problem

I’m the opposite - you know the photos of a car driving into a river? That’s me if the satnav said to drive into the river who I’m I to question it?
 
There actually was that potential here a decade or more ago. It's still drawn that way on the free version of the OS maps.

Imagine you're approaching the village from the south-west on the A702, heading for a destination on the south part of Main Street. See that blue line, the Lyne Water? See how it seems to be crossed twice, once by the A702 itself, and once a little way south of that, by an unnamed road (actually Chapel Brae)? You can see how it appears that the more southerly crossing would be quicker? Right?

It's a ford. Here is how Chapel Brae ends. You'd need a tractor. Or a horse.

I don't know if anyone was actually stupid enough to try it. But I haven't seen a satnav suggest that for ages. Google maps certainly doesn't.

I can see how the behaviour you describe could be problematic. I can only say I've been all over the damn place using Google maps (via Android Auto) for more than a year, and 99% of the time it has been absolutely gobsmackingly on the nail.
 
A few years ago, my uncle was complaining about his sat-nav. I'm not sure if he was using Google Maps, or some other system.
He lived on a bluff over a lake. There was a road around the lake below his house. whenever he left the house, his sat-nav instructed him to drive forward out of his driveway, off the cliff, to reach the road below.

I think the solution was to set waypoints in his sat-nav.

It's been a few years, so (hopefully) that's been fixed. But it's the type of error that you wouldn't want to be the first to discover on a self-driving car.

Another story:
Several years ago, a group of us had a conference we were attending at a ski resort. None of the navigation programs could seem to find us a route to get there. It started out with the built in navigation in the rental car, which took us in a repeating loop that never found the destination. So we tried using the navigation on various cell phones (android and then apple) each of which took us into a slightly different loop. Eventually, we had to get directions from another lodge we passed.
 
Public Transport is always safer per person and distance, simply because more people are in on vehicle going a predestined route with an experienced driver - statistics are unambiguous.

And there is no "last mile" problem if you are wiling to use public bikes or scooters. Also, if you spend a fraction of the money people spend on cars on increasing public transports, coverage can become much denser.
As long as you're not living in urban sprawl, US style, it's more of a last 100 yards problem, which is scarcely one.
 
I don't like walking for 20 minutes in pouring rain carrying stuff.
And I don't like negotiating busy streets full of cars as a pedestrian or cyclist. I don't like cycling past lines of parked cars whose drivers may open a door at any second or having to squeeze between them to cross the road. I don't like the proliferation of car parks and the concrete flyovers cutting through communities.

If you've got a heavy load to move, use your car. It's fine. But if everybody stops using their cars when they don't need to use them, our urban spaces would be much more pleasant.

I prefer the sheep personally. Unlike tourists they know to step out of the middle of the road.

This is definitely true. But, because I am from out the country myself and drive a lot of back roads, I don't mind this problem (it is definitely a problem).

So ◊◊◊◊◊◊◊ what? You are one person who lives in the sticks. Most people live and/or work in urban spaces. Are we supposed to base our transport policies based on what you personally want?

As I have said before: nobody is going to ask you to give up cars when they are necessary.
 
On the contrary, it seems many people want to base transport policy entirely on what is appropriate for city dwellers.

I want to base transport policy in cities on what is appropriate for city dwellers and country people just visiting. I have not seen anybody argue for the complete abandonment of cars. It's a straw man.
 
I've seen plenty of that.

It gets everywhere. I even remember taking three friends (so a full car) into Edinburgh for a music workshop, from a village that has at best one bus an hour, which takes ages because it zig-zags across the landscape to pick up and drop passengers at a number of villages and towns. Someone said, of course we really should be taking public transport. She was that brainwashed. Why? I asked. Er, pollution, she said. I pointed out that she was sitting in an electric car. Er, um. You might say congestion, but we had four people in a not-very-big car. But still some be-kind handmaiden thought we should have spent several hours on a bus, after walking a mile in the rain to get the thing. And a couple of hours hanging around because the timetable of course never fits in with the timings of events.
